NEP390 Handheld Turbidity Meter

The ANALITE 390 series of microprocessor based handheld turbidity meters are designed for applications where turbidity levels of up to 1,000NTU may be encountered. Ranges can be set by the user at 40NTU, 100NTU, 400NTU and 1,000NTU. There are four probes available which complete the ANALITE 390 series: NEP390, NEP391, NEP395 and NEP396 which can all be operated at depths of up to 100 metres (approx 330 feet).

Where applications are required in fast cold running water or for short monitoring deployment the NEP390 and NEP391 turbidity meters are ideal. Where bio-fouling and sedimentation build up is likely to be encountered the NEP395 and NEP396 turbidity meters have been specifically designed with an integral wiper assembly which can be initiated automatically (periodically) via a direct RS232 command or manually as required.

All turbidity probes almost totally reject fluctuating ambient light conditions due to a unique modulation technique. Plus use 90?optics and employ infrared light in accordance with ISO7027.

Calibration can be carried out at any time or have later firmware uploaded by the user via the RS232 interface.

Two cable connection systems are available. The standard version employs a marine grade connector to terminate the cable to the turbidity probe, whereas the G version has the cable permanently connected to the probe via a waterproof gland.
