Rugged, Reliable and Cost Effective Water Monitoring

Tethys Instruments’ (France) cutting edge UV400 and UV500 water monitoring systems designed with high reliability and low operating costs specifically in mind.

Based on a modular system, a wide range of cost-effective configurations are available from mono-parameter to multi-parameter (UV400), and even with full UV spectrum (UV500).

Using UV spectroscopy for the main parameters (Ammonia, COD, Nitrate, Hydrocarbons), the UV400 and UV500 are especially suited for monitoring water treatment plants, process control, industrial inlet/outlet systems, rivers or industrial effluent. These new monitoring systems will measure most parameters in around 5 seconds.

The new instruments offer a great array of advancements over the previous Tethys’ Models, whilst maintaining a compact size of (520 x 390 x 220 mm). All parameters fit in one enclosure, including ammonia and phosphate and the new patented flow cell is virtually clogging proof even with an ultra high level of suspended solids. Users will find the new colour touch screen interface extremely fast and user-friendly. These instruments offer new faster measuring time and improved repeatability by the use of a new high performance DSP (Digital Signal Processor).

The inside of the analyser is very accessible, which makes cleaning components, such as the flow cell, very simple. The mono-board format also makes electronic maintenance a simple task. A USB port to download measurements, a diagnostic data on a USB memory stick, RS232 and RS485 ports are included, whilst Wifi and Ethernet interfaces are available as optional extras.

Tethys’ new instruments can measure up to 16 parameters. No reagent is required (except NaOH for NH4+, HCl for dissolved H2S and usual reagent for PO4 ). These units, which include a automatic cleaning system, can operate with unfiltered waste water, or even activated sludge. The instruments also feature automatic turbidity compensation for COD, nitrate, hydrocarbons and phosphate, as well as an auto-zeroing function.
