# Hazardous-area moisture analyser: trace dew point in classified areas

Trace moisture and dew point measurement is available for classified areas on the ACCURRA-Hz platform. Please ask us for the current configuration and certificate scope.

- ISO 9001:2015, certified by TÜV
- Designed and built in Pune since 2002
- Supplied to Reliance, Tata Steel, Indian Oil, Linde and ISRO

 Quick answer

Trace moisture measurement for classified areas is handled on the ACCURRA-Hz platform. Contact Sarvesh for the current configuration and certificate scope. The safe-area M015 reads minus 80 to plus 20 C dew point if you can sample to a safe-area house.

## Key features

- Dew point or ppm moisture in classified areas
- Alarm relays and outputs
- Same platform and diagnostics as ACCURRA-Hz

## How it works

Moisture in hydrogen, in reactor feed and in solvent systems affects product quality and safety, and the plants that care are classified. Moisture measurement in such areas uses certified equipment, or a sample taken to a safe-area house.

The safe-area moisture analyser M015 reads from minus 80 to plus 20 C dew point with a ceramic sensor. For classified areas, please contact us with the area classification, gas and dew point range so we can confirm the configuration and certification that applies.

## Requirements and limits

- Please confirm the hazardous-area moisture configuration and its certificate scope with us before ordering.
- Field calibration is not possible on the safe-area dew point model M015.

## Selection guidance

Choose this route for product hydrogen from electrolysers, reactor feed gas and dryers in classified areas. If a safe-area house is available, M015 can also be used.

## Frequently asked questions

**Is a hazardous-area moisture analyser available?**

Please ask us for the current configuration and certificate scope for your classification.

**What range?**

Safe-area M015 reads minus 80 to plus 20 C dew point.

**Can I use a safe-area analyser instead?**

Yes, if you can sample to a safe-area house.

**Can I calibrate dew point on site?**

Not on the safe-area M015, where field calibration is not possible; please ask us.
