PD8-7000 ProtEX-MAX Explosion-Proof Temperature Meter

Brand: Precision Digital Corporation

Front, back and in between, the PD8-7000 ProtEX-MAX explosion-proof temperature meter boasts specifications, features and functionality that make it the only hazardous area temperature meter you will ever need.

The first thing you notice about the PD8-7000 is its modern looking, rugged, explosionproof housing with convenient mounting flanges, available in aluminum or stainless steel. Housed inside this enclosure is a dual-line, 6-digit display with high-intensity LEDs that can be read in direct sunlight.

The PD8-7000 has all the same features as our PD7000 1/8 DIN temperature meter, as a fully approved explosion-proof product. The product is certified by CSA as Explosion-Proof / Dust-Ignition- Proof / Flame-Proof, and is ATEX and IECEx certified as Dust-Ignition-Proof / Flame-Proof.

The ProtEX MAX PD8-7000 can be programmed by the user to accept type J, K, T, E, R, S, B, N, and C thermocouples as well as 100 or 1000 Ω platinum, 10 Ω copper, and 120 Ω nickel RTD inputs. The meter’s six-digit display allows it to display the higher temperature thermocouples up to their standard Fahrenheit range, such as 2400 degrees for the Type K thermocouple.

The user can also set the meter to display in Fahrenheit or Celsius and set the resolution to 1 degree or 0.1 degree.

One of the most common applications for the PD8-7000 with the isolated 4-20 mA output is to act as an explosion-proof temperature transmitter with a big display. The meter will also capture the maximum and minimum readings.

Finally, all these features and capabilities can easily be programmed without removing the cover using CapTouch buttons in a hazardous area or with free MeterView Pro PC-based software in a safe area.
