Palmer Wahl 329AHP | 392AHP High Performance Platinum RTD Meter | -290 to 1450°F
Part 329AHP is the Palmer Wahl 392AHP high-performance Heat-Prober platinum RTD meter. It traces the DIN 43760 platinum standard to 0.1°F conformity across a -290 to 1450°F (-180 to 788°C) range, and automatically compensates for each HP probe's ice-point and alpha calibration, so extra HP probes can be added without recalibrating. Typical uses are calibrating installed sensors, quality assurance tests and precise process measurements.
Key features
- Meter accuracy ±0.1°F/°C at 32°F (0°C)
- System accuracy greater of ±0.2°F or ±0.25% of reading with 202HP probe
- Readings updated 2.5 times per second
- Noise rejection program for strong EMF such as spark ignition engines
- Drop-tested meter, 0.33 in LED display
Offered in Fahrenheit, Celsius and dual-scale versions with a 4-pin DIN female probe connector. Add -E for a European plug adapter. Pairs with CAL392HP calibrators.
