The Martel PTC-9002
is a full function thermocouple/RTD calibrator combined with the ability to
simultaneously read and display a 4 to 20 mA current loop. These features make
it ideal for calibrating all types of temperature measuring devices and
transmitters.
Housed in a rugged hand-held case, the PTC-9002 features
0.5°C accuracy on the most commonly used T/C and RTD ranges. Up to nine (9)
setpoints can be stored in non-volatile memory for each of the seven ranges. An
auto-step function allows the user to automatically step through each of the
stored setpoints for a particular range at a predetermined interval.
Resolution is .1°C/.1°F on all temperature ranges
and .001mA on the milliamp range. An internal 24 volt loop power supply allows the user
to power a two-wire transmitter and read the out-put current. No external loop
power is required.
Each unit includes: Test leads, carrying case, 4
alkaline AA batteries, instruction manual, and NIST Certificate. |
