Differential pH electrodes designed for pH measurements in very difficult applications where standard pH electrodes cannot work because the reference electrode life would be too short as, for example,  those processes including fouling  or fatty substances that  would deposit on the reference electrode making the measurement impossible and processes containing substances that react with traditional reference electrodes destroying them, such as Hg++, Pb++, Cu++, ClO4-, Ag+, Br-, I-, CN-, S= ions. These sensors are fully interchangeable with any other pH electrode and are suitable to be used with any pH meter and even with voltmeters and PLC. An economically interesting solution is the use of these sensors in conjunction with our standard pH meter Mod.uP01, uPLT01, uP01R, TX01, TX-HMI 01.

Differential ORP electrodes designed for ORP measurements in very difficult applications where standard ORP electrodes cannot work because the reference electrode life would be too short as, for example, those processes including fouling or fatty substances that would deposit on the reference electrode making the measurement impossible and processes containing substances that react with traditional reference electrodes destroying them, such as Hg++, Pb++, Cu++, ClO4-, Ag+, Br-, I-, CN-, S= ions. These sensors are fully interchangeable with any other ORP electrode and are suitable to be used with any ORP meter and even with voltmeters and PLC.

Multiparametric analyser designed for on site measurements of all most important chemical and physical parameters useful to characterise the quality of a water. It can be used both for spot measures and for long term measurements. Mod.345 AQUAMASTER is composed of a surface unit and an immersion probe. The surface unit is a splash-proof (IP-56) plastic box provided with a soft carrying case with handles allowing hands-free operation. It inclucles a sealed compartment for the rechargeable battery pack and line power supply / battery-charger. If needed the instrument can be also operated with an external 12V battery. A waterproof membrane keyboard allows an easy programming and parameters selection. All data can be read simultaneously on back-lighted LCD. The instrument can be operated as a real-time multimeter or as a data logger, storing data at intervals between 10 seconds and 24 hours.

Multiparametric analyser specifically designed for on site measurements of all the most important chemical and physical parameters useful to characterize the quality of water. The system is suitable to measure in fresh water (rivers and lakes), salt water, wells and clarified wastewater. The complete measuring system includes the multiparametric probe, (Mod.346/P - complete version that can include sensors of pH, ORP, ISE, Conductivity, Turbidity, Dissolved Oxygen, Pressure, Temperature and the stirrer - or Mod.346/PS simplified version that can include sensors of pH, ORP, Conductivity, Dissolved Oxygen, Pressure, Temperature and the stirrer) the cable with sealed connectors, the instrument Mod.346/SU (datalogger c/w data transmission system via RS232 serial interface or via radio or via Modem GSM) or the instrument Mod.346/IU (pc interface c/w RS232 serial link or Modbus); PC or PLS (these last two are to be supplied by the customer).

Microprocessor based PID controller, fully programmable, suitable for panel mounting (IP54 protection degree) and outdoor installation (IP65 housing). Instrument configuration is easily performed via display and keyboard and calibration is automatic. Measure and temperature are indicated on a 5 digit red LED display. Mod.uP can be directly connected to pH, ORP or ISE sensors and to the pertinent temperature sensing element. The measure is compensated for temperature variations, according to dedicated algorithms specific for each parameter and displayed in engineering units. Temperature compensated value is used in the PID algorithm. The PID controller is available either with analogic control output (4-20 mA or 0-10V, galvanically isolated) or with digital control output (conatct output); in this versione the 4-20 mA (or 0-10 V) output is available for temperature compensated measure retransmission.

Simple and combined pH electrodes, for laboratory use and for industrial applications, Mod.101.  Simple and combined electrodes for the measure of pH, suitable for laboratory use and industrial applications.

Simple and combined ORP electrodes, for laboratory use and industrial applications, Mod.201. Simple and combined electrodes for the measure of Oxidation Reduction Potential (ORP), suitable for laboratory use and industrial applications.

PID controller for pH (Sb probe) control Mod.uPxxR. Microprocessor based PID controllers, fully programmable, suitable for panel mounting (IP54 protection degree) and outdoor installation (IP65 housing). Instrument configuration is easily performed via display and keyboard and calibration is automatic. Measure and temperature are indicated on a 5 digit red LED display. Mod.uP can be directly connected to the sensor of pH with antimony (Sb) electrodes and to the pertinent temperature sensing element. The measure is compensated for temperature variations, according to dedicated algorithms specific for each parameter and displayed in engineering units. Temperature compensated value is used in the PID algorithm.

Through flow fitting for pH measures with antimony electrodes, Mod.Sb0A. Mod.Sb0A probes are designed for all those processes where glass pH electrodes would not be suitable, for example in fluids containing abrasive or fouling substances and in processes with high concentration of hydrofluoric or phosphoric acid. These probes are made of PP (PVDF on request) and have ½` F process connections; they are supplied c/w bracket and accessories for wall mounting and are extremely easy to install. An electrolyte reservoir housed in the upper cap assures long operating periods with no refilling requirements.This probe includes, besides the temperature sensor for measurement thermocompensation, separate electrodes: the antimony electrode is anular with flat surface and the reference is Ag/AgCl, with flat shaped diaphragm.

pH probe with antimony electrodes for direct installation in closed pipelines, Mod.Sb0D. Probe Sb0D has been developed for pH measurement in specific applications where a standard glass pH electrode would not be suitable, for example in fluids containing abrasive or fouling substances and in processes with high concentration of hydrofluoric or phosphoric acid. The probe is made of AISI 316 SS with PVDF electrodes support (Mod.Sb0D0x2xxAx) or in PVDF with PVDF electrodes support (Mod.Sb0D0x4xxAx)  and includes flanges for direct in line intallation, with different pipe sections.
