DPT-CR-MOD is a differential pressure transmitter with Modbus  communication designed specially for cleanroom monitoring. In addition  to differential pressure, the device enables monitoring temperature and  relative humidity. A 0…10 V voltage input of an external humidity and  temperature transmitter (for example Siro-rH-T) can be connected to the  input terminal of the device. In this case, all three measured values  (differential pressure, relative humidity, temperature) can be shown  simultaneously on the display. Alternatively, a passive temperature  sensor can be connected to the input terminal.

Siro-MOD is an indoor air quality transmitter with a modern design. The transmitter is available with several optional air quality sensors. The modular device can be equipped with CO2 concentration and VOC (Volatile Organic Compounds) measurements or alternatively PM (Particulate Matter) measurement, and in addition, temperature and humidity measurements. It offers easy installation and adjustment, several different model options and various output signals that are configurable separately for each measurement parameter.

Configuration is also possible via Modbus network. Siro-MOD utilizes the industry standard NDIR measurement principle with self-calibrating ABC logicTM for CO2 measurement.

Siro-MOD series devices include:

• Several options for indoor air quality measurements (CO2, VOC, PM, rH, T).
• Field configurable outputs for selected measurements.
• Proportional output options including voltage (0–10 V, 0–5 V, 2–10 V) and optional current (4–20 mA).
• Offset feature enabling field calibration for each measurement parameter (CO2, VOC, PM, rH, T).
• Optional LCD-display and buttons.

DPT-Priima is a high accuracy differential pressure transmitter  designed for cleanrooms and other demanding applications. DPT-Priima has  a new, extremely accurate sensor and automatic zero point calibration,  and optional span point calibration.

DPT-Priima together with SPP (static pressure port) is a complete solution for building envelope measurement.

RHT-MOD Duct is a relative humidity transmitter with temperature output installed in air ventilation duct. In addition to these measured values, RHT-MOD Duct calculates various parameters such as dew point, mixing ratio, enthalpy and absolute humidity. Illuminated display ensures easy readability also from a distance. The RHT-MOD has a screwless lid and an easily adjustable mounting flange that make the installation of the device easy.

RHT-MOD Duct series devices include:

• Separate Modbus output for all measured and calculated parameters (relative humidity, temperature, dew point, mixing ratio, enthalpy and absolute humidity).

• Offset feature enabling field calibration for measurement parameters rH and T.

• Mounting flange

• Clear backlit display

HML and HML-N carbon monoxide transmitters are designed for measuring carbon monoxide in underground parking garages and parking halls. The measuring cell is an environmentally friendly electro-chemical cell with a long life, good long term stability, and high accuracy. As the sensor is heated, the transmitter is working also in temperatures > -30°C. The output of 0…10 V or 4…20 mA is available on the ranges of 0…100 or 0…300 ppm CO concentration for controlling ventilation.     The recommended transmitter calibration interval is one year. HMV exchange kit can be used to ensure the correct transmitter function. A new calibration report is delivered with the exchange kit.
