Model PT205 -Hydrogen Sulfide Sensor
The PT205 Hydrogen Sulfide Sensor is designed to detect Hydrogen Sulfide in air and provides an analog output signal. The PT205 uses electrochemical cell technology to detect H2S in parts per million (ppm).
The complete H2S sensor consists of the following: a stainless steel sensor head assembly, a user connection board and a transmitter board assembly. All of the sensor`s electronics are enclosed in an explosion proof instrument box. The detector modular design allows easy maintenance, troubleshooting and high reliability. The low power microprocessor based sensor transmitter provides a 4-20mA analog signal proportional to 0 - 100% of the detection range of the sensor. Not to mention, that an LED indicator on the transmitter board provides sensor status and fault condition.
