Mercury Honeywell temperature recorders are available in 8-inch and 12-inch charts with temperature ranges of 100°F up to 1,000°F and lower limits of -30°F.
Honeywell Mercury 8-inch chart recorders and 12-inch chart recorders are available for temperature range spans of 100F (55C) up to 1,000F (550C), and lower limit of -30F (-34C).
One or two pen recorders are available in both the 8-inch and 12-inch configuration, calibrated to English or metric units. Temperature recorders come in-wall, flush, or pipe-stand mount and also in portable models.
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.
