The instrument is provided with three inputs for probes with SICRAM module: the probes have an electric circuit that communicates with the instrument; the sensor calibration data are saved in its permanent memory. All the SICRAM probes can be inserted in one of the inputs: they are automatically recognized when you switch the instrument on.
The main features of the instrument are:

• Logging: acquisition and memorization of data inside the instrument. Memory capacity: 64 different logging sections, with the possibility to set the acquisition interval of the samples. You can set the duration of the memorization and, with auto-start function; it’s possible to set the starting and finishing date and the hour of data memorization.
• The measurement unit of the temperature visualized sizes: °C, °F, °K.
• The system date and hour.
• The visualization of the maximum, minimum and medium statistic parameters and their cancellation.
• The transfer speed of the data through the serial port RS232.

HD32.2 instrument can contemporarily detect the following sizes:

• Globe thermometer temperature Tg.
• Wet bulb with natural ventilation temperature Tn.
• Ambient temperature T.

On the basis of the detected measurements, HD32.2 can calculate:

•  WBGT(in) index (Wet Bulb Glob Temperature: wet bulb and globe thermometer temperature) in presence or absence of solar irradiation.
•  WBGT(out) index (Wet Bulb Glob Temperature: wet bulb and globe thermometer temperature) in presence of solar irradiation.

These probes are requested for the WBGT measurement:

• Dry bulb temperature probe TP3207.2.
• Globe temperature probe TP3276.2.
• Natural ventilated wet bulb temperature probe HP3201.2.

HD32.2 is the portable version, mostly used in combination with a table stand (small tripod). For measurements during a longer period we suggest the version with a stable tripod HD32.3A.

The probe measures the carbon monoxide concentration in air. Together with the HD320B2 probe, the HD320A2 probe allows analyzing and monitoring the air quality in internal environments and detecting any loss of CO.
The sensor for the measurement of CO consists of an electrochemical cell with two electrodes.

Measuring range 0 ÷ 500 ppm.

Cable length 2m equipped with SICRAM module.

The probe is calibrated by the company and, usually, doesn’t request any intervention by the user.

A magnetic support (HD320AS2) can be used for fixing the probe HD320A2 to the housing of probe HD320B2.

The post HD320A2 – CO Carbon Monoxide Probe appeared first on Senseca.

The probe measures the carbon dioxide concentration in air. It’s indicated for checking and monitoring the indoor air quality. Typical applications are the check of the air quality in all the buildings where there is a crowd of people (schools, hospitals, auditoria, canteens, etc.), in the working places to optimize the comfort. CO₂ measurement is obtained with an infrared special sensor (NDIR technology: Non-Dispersive Infrared Technology) that, thanks to the use of a double filter and a special measurement technique, warranties precise, stable and long-term measurements. The air to check is spread inside the measurement chamber through the protection membrane placed at the top of the probe.

Measuring range 0 ÷ 5000 ppm. Cable length 2m equipped with SICRAM module.

The probe is calibrated by the company and usually doesn’t request any intervention by the user.
