in calibration, placement and use of gas
sensor modules to ensure accurate and
reliable monitoring of hazardous gases.
CALIBRATORS
1200-26 Calibration Gas Delivery System
The Model 1200-26 Calibration Gas Delivery System provides
calibration gas for Combustible Gas, Carbon Monoxide, or Oxy-
gen Deficiency gas detection monitors. This system consists of
disposable pressure vessels (2 cylinders supplied with each sys-
tem) containing calibration gas and a non-disposable pressure
and flow regulation system. Gas flow is controlled in two steps
with a regulator and flow meter to conserve gas and to accu-
rately regulate flow.
The 1200-26 and the Methane calibration gas cylinders are ap-
proved for calibration of FM Approved Sierra Monitor Combus-
tible Gas Sensors.
1250-XX Calibrator Kit
The 1250-XX Calibrator Kit is used to deliver calibration gas for
combustible gases and a wide variety of toxic gas detection
modules including Carbon Monoxide, Hydrogen, Combustible
Gas, Hydrogen Sulfide, Chlorine, Sulfur Dioxide, Nitric Oxide,
Nitrogen Dioxide and Zero
Grade Air. Other gases are
available, contact Sierra
Monitor for the latest infor-
mation. There are three
versions of the calibration
kit available depending
upon the specific calibra-
tion gas required. Each kit
contains a regulator, cali-
bration adapter and carry-
ing case. The individual
calibration gas cylinders
(Series 1260) are sold
separately.
9210-00 Permeation Type Calibrator
The 9210-00 Permeation Type Calibrator with the individual per-
meation tube for the specific gas required offers a unique means
of generating a desired gas. This device has the advantages of
a wide selection of gas types, long life, and is an economical
solution for the regular calibration of a large number of toxic
sensors. Most popular applications are ammonia and hydrogen
sulfide.
