Features & Benefits

Temperature Recorders

The mercury-filled temperature system manufactured by Mercury Instruments offers the ultimate for accuracy and durability in a temperature recorder. This is credited to all-welded steel construction with uniform scale deflection and rapid response to temperature changes. The standard case compensated system is used for capillary lengths of up to 25 feet. A fully compensated system is a necessary option for greater capillary length. The accuracy of each temperature recorder is +-1 chart graduation.


Full-length stainless steel armor protects the capillary from damage for the entire exposed length. A 1/2" NPT union on a 10-1/2" adjustable length stem permits the insertion of the 5/8" diameter bulb to full depth in the thermowell. Standard thermowell is threaded 3/4" or 1" NPT, brass or 304 or 316 stainless steel, 4", 6", 8" or 11" length. Specify size and material.
