GMI 111 REPLACEMENT COVER WITH
DIGITAL DISPLAY FOR GMP 111 & 111E
A direct replacement for the front cover of the GMP
111 and GMP 111E. Its four-digit LCD display reads
to the nearest ppm. It connects directly to the nine
pin connector on the transmitter electronics and can
be used as a digital indicator or as part of a calibrator.
FIELD CALIBRATION KIT
Made up of six calibration balloons, a hand pump
and a calibration tube, it supports both one and two
point calibration. In one point calibration ambient air
is used as zero gas; in two point calibration the
customer creates span gases using exhaled breath.
Output of the transmitter is checked using a common
DMM or the GMI 111. The transfer standard is the
GM 12 portable meter. Quick and easy to use, it
permits two point calibration without using heavy
gas bottles.
PROTECTION SHIELD FOR GMP 111/111E
This protection shield prevents the ingress of water
into the gas sample chamber during spray or wash
down, providing protection of the sensor without
impacting response time. It snaps in place and can
be removed easily for cleaning or maintenance.
