Protea - Model HPS -Heated Sample Probe

Heated sampling probe for the determination of particulate matter and chemicals in the gas phase. It’s unique design, combined with the clamps-free slide and lock device, allows the probe to freely rotate around it’s axis, needed for the swirl angle determination in accordance with the EN16911 and US EPA M1/2, while making it easy to move it with just two fingers.

Also, the probe can be fixed, in few seconds,to the hub in two different positions for common vertical stacks or for horizontal stacks, without the need of any further device.

• Built in accordance with the main international methods such as :
• EN UNI 16911 velocity and flowrate in ducts

• EN ISO 1948-1 Dioxins/Furans and PCB
• EN UNI 13211 Total Mercury
• EN 14385 Heavy Metals
• US EPA Method 1-2-5

• Modular assembling, rugged and easy to use
• Ready for swirl determination (digital inclinometer needed)
• Integrated type “S” Pitot tube
• Suitable also for horizontal ducts
• Heated cartridge sealed AISI 304 steel

Heated Probe for Micropollutants sampling

All the elements exposed to stack fumes are realized entirely AISI 316 stainless steel.

All the pneumatic and electronic connections are integrated in the compact single block structure.

The Pitot tube and thermocouple are integrated within the probe body, more rugged more easy to use on stacks.

With the HP5 it’s possible to use internal suction tubes
made in :

• Titanium GR2
• Borosilicate glass
• Quartz

Maximum operative temperature of 400°C Pitot terminal not included

The HP5 is designed to be upgraded in relatiion to the application. It’s modular design allows to add parts and devices to allow the sampling of different parameters simultaneously using only one probe.

A samples distribution center. One probe, many sampling ways! When only one stack port is available, those practical and functional solution greatly decrease the stack monitoring required time since the sample is simultaneously distributed to different equipment for collection or analysis.

Single or multiple derivations

Beside classic PM sampling, the probe can be equipped with single or multi-derivation device built in Titanium to capture all the chemical parameters in compliance to official methods, such as EN14385, EN13211, EN14791, EN1911, ISO 15713.

Practically, after filtration of the particulate matter, from main the gas stream is possible to extract from 1 up to 4 aliquots with lower flowrates (0,5 to 2 lt/min) sampled by constant flow pumps and sent to impinger train/s in order to capture the chemicals.

If multiple derivations are necessary, a special 4DL Hub is required to allocate filterholder and the 4DL device.

To the 4DL Hub is possible to mount a support which enables the positioning of two athermal boxes for a maximum of 4 impingers trains.

The HP5 sampling probe can be equipped with a second internal sampling line dedicated to gas sampling. This practical solution allows to use the same isokinetic heated probe also to extract a gas using a secondary constant flow sampling line or real-time monitors such as FID, FTIR or combustion analyzers.

Just connect the sampling/monitoring equipment to the outlet of the gas line placed on the back of the probe.

For FID analyzers or Total VOCs sampling, dado lab designed a practical and light probe, named HP1, which filter housing, heated up to 180°C, can be connected to the HP5 to condition the sample in compliance to the EN12619-2013 for VOCs analysis or sampling.

THe HP1 filter hounsing is available with one or two outlets for heated lines allowing to connect two analyzers or two sampling lines. For more details about the HP1 probe, check datasheet 101.105_HP1.

HUB HP5 is the “connecting” device for all the items composing the heated sampling probe.Inside the box, are placed the different filtering devices made of titanium, quartz or glass.

The Hub is built in AISI304 stainless steel and aluminum, with protection painting

The thick insulation allows to operate at temperatures of 150 - 180 °C

The locking system of the hub allows to place the probe/Pitot in vertical or horizontal position.

Moving the probe is easier and safthanks to the two handlings easy.

Titanium, Glass or Quartz Filterholder for 47mm flat membranes or thimbles. The filter membrane is placed inside the filterholder cassette which makes it very fast and practical to change. Geometry and wide tight surface decrease the risk of accidental filter breaking.

Titanium, Glass and Quartz 47 mm Filterholder with side stream option Allow to extract an aliquot of sample inside in the heated box in compliance with international methods asking for one or more derivation of the main isokinetic stream Available in both glass and quartz.

With this device, moving the heated probes, even the longest, along the stack axis, isn’t a problem anymore.

It smoothly moves on three rollers without friction but grants at the same time position stability and isolation from stack fumes.

Completely built in anodized aluminum, the overall weight is less than 1.5 kgs.

The fixing flange can turn on the probe axis, allowing to align the probe correctly independently from the holes of the stack port. This device is compatible with stack ports from 4” to 5” (DN80, DN100 and DN125).

The type “S” Pitot terminal (Darcy) is entirely made of AISI 316 steel and equipped with double ring connections. Every piece is marker with unique serial number for the identification and traceability of the certification. The particular asymmetric shape is made with the purpose to easily identify the probe positioning respect the flue gas direction. Every terminal is supplied with the report including the calibration constant. On request, is possible to supply the Accredia certification.

This option allows a fast and easy determination of the swirl angles to be entered in the ST5 for the evaluation of the cyclonic flow.

This battery rechargeable device can be fixed to the hub with its support and lets your hand free to turn the probe for the 0 dP point.

Allows the connect directly, and without tubing, the hot filterholder to the impinger train, as requested by EPA5 or by the most recent EN methods for the determination of micropollutants in flue gas emission.

The box is fixed directly to the Hub without using any screws or bolts.

It’s built in AISI304 stainless steel and aluminum while the impinge cooling bath is made in polypropilene.

The cover is made to protect and insulate the box for a safe and practical transport back to the laboratory.

The HP5 probe is designed to quickly replace the inner tube with others made of different material in order to be in compliance with the different standards for micropollutants sampling along with particulate matter.

Realized with a smaller diameter to decrease the deposition effect and increase the recovery in laboratory, the inner tubes are available in AISI316 steel, Titanium Grade 2, Quartz or Glass.

The FC5 condenser is built in accordance with the requirements defined in the EN1948 for the “Filter/condenser” method and to EPA23 with the dedicated option to invert the cartridge with the water flask.

The trap is equipped with a glass support for the use of PUF or XAD2.

The device is extremely compact, the adsorbing trap allocated inside the cooling device, this allow an increased cooling capability, UV protection and damage protection.

The FC5 is supplied with a shock proof case.
