GAS DETECTORS > ETHYLENE OXIDE
M1 Gas Monitor with Stainless Steel Sensor Head configured for Ethylene Oxide EtO (C2H4O) Range 0-20 ppm with Alarm board with 5A form C relay for 3 alarms, 4-20mA output transmitter.
The GDS Corp Model M1 Gas
Monitor detects combustibles, toxic
or oxygen levels and displays
calibrated values in engineering
units on a 3 1/2 digit LCD readout.
Easily replaceable sensors and
options that include MODBUS®,
5A form C relays and isolated 4-
20mA outputs enable the M1 gas
monitor to satisfy the most
demanding gas detection
applications.
Non-intrusive magnetic zero / span
controls allow one-person
calibration without opening the
enclosure or declassifying a
hazardous area. A built-in postcalibration
or power-up delay locks
the 4-20mA output to eliminate
false alarms due to calibration
span gas or sensor stabilization.
Three M1 models are available.
The M1/LEL accepts catalytic bead
combustible detectors; the M1/EC accepts low
level electrochemical sensors and the M1/mA is
wired to accept an external 4-20mA current loop
input. Each M1 features a standard 4-20mA
output. Option boards include three 5A form C
relays, MODBUS interface or isolated 4-20mA
output.
A “Unity” control resets ZERO and SPAN
settings to the middle of their range and clears
any internal gain and offset settings. Diagnostic
messages on the LCD indicate modes such as
FAULT, CAL, DELAY and ESL (end of sensor
life).
Available Ranges
Options:

Explosion Proof
Installations.
- Standard 4-20 mA
output transmits
1.5mA “In Cal”
signal.
- Non-intrusive one-person
calibration
