| Model | PM880 Portable Hygrometer/Moisture Analyzer |
| Other Humidity Parameters | The range and accuracy of absolute humidity (mH20/v) and relative humidity (e/esat) readings are based on the fundamental dew point and temperature measurements. The range and accuracy of mass (ppmw) and volume (ppmv) ratios are calculated based on the fundamental dew point measurement and pressure and gas molecular weight constants. |
| Repeatability | 0.05°C |
| Display | Two simultaneous parameters with 0.01°C resolution. “Dew Layer Thickness,” “Control,” “Alarm” and “Service” indicators |
| Analog Output | Two linear simultaneous parameters. 0/4 to 20 mA (isolated) with 250W max load |
| Alarm | Form C (SPDT) 7 amp, 30 VDC (resistive load) |
| Digital Interface | RS-232 |

How does it work?
The PM880 hygrometer is a complete, intrinsically safe, portable system with options and accessories to meet all industrial moisture measurement needs.
This hygrometer is small, lightweight, and easy-to- use. The large LCD displays moisture readings in dew point (°C or °F), ppmv, ppmw, lb/MMSCF (natural gas) and a variety of other unit options. Data can be viewed in alphanumeric or graphic formats. A rechargeable battery pack and battery charger make this the ideal go-anywhere moisture analyzer.
The PM880 comes in a soft carrying case with zippered compartments, a handle and a shoulder strap. The case accommodates the PM880, a sample system, flexible hosing, probes with protective covers, a Moisture Image Series probe electronics module, an operating manual, a battery pack, a battery charger and probe cables.
Training for the PM880 is available on-site, in the factory or online. GE offers extended warranties and service agreements for the PM880 as well as a range of services including NIST-traceable calibration, field calibration, rentals and moisture surveys.
