SENSOR TYPES AND PUMPS
Combustible Gas Sensor
All
SENSIT® GOLD G2
instruments incorporate a highly sensitive and
uniquely designed semiconductor sensor. The function and accuracy of
the sensor are monitored and controlled by specialized circuitry and a
microprocessor. This sensor is capable of measuring concentrations
of as low as 1ppm methane up to 100% LEL. When equipped with the
percent volume sensor, concentrations above 70% LEL are monitored
or measured simultaneously with a state-of-the-art thermal conductivity
sensor (TC). This sensor is capable of measuring high concentrations
of gas quickly and accurately. All readings are automatically switched
between the scales of PPM (if so equipped), LEL and percent volume.
Electrochemical Sensors (optional)
All
SENSIT® GOLD G2
instruments when equipped with the following
optional sensors, microprocessor and associated circuitry will measure
oxygen levels from 0-25%, measure carbon monoxide (CO) levels from
0-2000ppm and measure hydrogen sulfide (H2S) levels from 0-100ppm
or hydrogen cyanide (HCN) levels from 0-30ppm. All gases are displayed
simultaneously on the display.
The Pump
The
SENSIT® GOLD G2
instruments are equipped with a powerful
and efficient pump. A water/dirt filter at the end of the gooseneck
protects the pump from foreign material. An additional internal filter also
helps to protect the pump from damaging debris. There are audible and
visual indicators that will show a blocked or improperly operating pump.
NOTE:
Operating the instrument without a sensor cap or with an altered
sensor cap can cause damage to the instrument and void the warranty.
