This precision immersion thermostat incorporates the
Klixon
® 3BT Tiny
Stat™ — the smallest, lightest,
fastest snap–acting thermostat ever made.
Quick response to rapidly changing temperatures is
a virtue of the low thermal mass series probes. The unique
Klixon 3BT Tiny Stat is located at the
end of the probe for ultimate sensitivity.

Notes:
1.) Devices which open on temperature rise should not be subjected to vibration while at temperatures of
75°F or more below the opening temperature.
2.) Devices which close on temperature rise should not be subjected to vibration while at temperatures of
75°F or more above the closing temperature.
