NEMA 4/IP65 SEALED METAL FRONT BEZEL
DESCRIPTION
The Apollo Thermocouple Indicator is a high accuracy, microprocessor
based instrument designed for low cost temperature measurement and control.
The microprocessor automatically compensates for cold junction, NBS
linearity, and the meter’s zero and span.
(One model accepts all thermocouple
types by simple programming.)
There is no need to recalibrate when changing
input types. Isolated analog output, serial communications, and temperature
alarms are available as low cost options.
The NEMA 4/IP65 designed, die-cast metal bezel of the Apollo can be sealed
in the front panel for use in wash-down and other tough industrial environments.
The full 4-digit display features large 0.56"
(14.2 mm)
red LEDs for easy reading.
