The following is a list of GMI sensors available for use with the Model 610A Controller:
PART NUMBER DESCRIPTION
10001-1 Standard Industrial Combustible Gas Sensor. Used for most
hydrocarbons and hydrogen. Temperature range –65°F to
+200°F (-55°C to +93°C).
10001-1R Same as Part Number 10001-1, except greatly improved
resistance to poisons, such as HMDS
(Hexamethyldisiloxane) and H
2
S (Hydrogen Sulfide).
10014-1 High Temperature Standard Industrial Combustible Gas
Sensor. Same as Part Number 10001-1, except sensor body
is stainless steel.
10058-1 Same as Part Number 10001-1, except sensor body is
stainless steel.
10058-1R Same as Part Number 10058-1, except greatly improved
resistance to poisons, such as HMDS
(Hexamethyldisiloxane) and H
2
S (Hydrogen Sulfide).
10022-1 Similar to Part Number 10001-1, except PTB approved.
10059-1 Same as Part Number 10022-1, except body is constructed
of stainless steel.
10015-1 High Temperature equivalent of Part Number 10022-1. It may
be used in temperatures up to 400°F (200°C).
