HydroTech - Model HT6 -Groundwater Monitoring
We manufacture the most rugged multiprobe in the world, the HT6, which is designed to handle extremely harsh environments. The HT6 is so rugged that it was selected to be used in the DepthX project on board an autonomous submarine built by StoneAerospace in collaboration with NASA and the Univerity of Texas to explore the moon Europa.

The HT6 is highly recommended for the following applications:
- Long-Term monitoring in high salinity water, marine environment, or desalinization plant
- Monitoring bodies of water deeper than 200 m
- Extra long deployment cable up to 4000 feet ( 1219.00 m ) ( Add-on option )
- Intensive use for ground water monitoring in 2" well or larger
- Deployment from or near a bridge or any structure with electromagnetic interference (EMI). The HT6 has absolute signal shielding from the sensor guard to the DB9 connection at the end of the cable.
- High velocity discharge areas
- Deployment in any harsh environment
- Deployment in high traffic areas
- Presence of alligators
- Fully encased in Titanium for maximum ruggedness and durability

Sensors:
The LDO sensor by Hach uses luminescent dissolved oxygen technology,
which has no membranes to maintain.
- Range: 0 to 20 mg/L
- Accuracy: +/- 0.1 up to 8 mg/L ; +/- 0.2 above 8 mg/L
- Resolution: 0.01 mg/L
The temperature sensor is a 30k ohm variable resistance thermistor.
The temperature sensor is included with every Hydrolab sonde.
- Range: -5 to 50 °C
- Accuracy: +/- 0.10 °C
- Resolution: 0.01 °C
The Conductivity sensor uses four graphite electrodes in an open cell design.
- Range: 0-100 mS/cm
- Accuracy: ± (0.5% of reading + 0.001 mS/cm)
- Resolution: 0.001
