In-Situ appoints Isodaq Technology as a UK distributor

Isodaq Technology, the product sales division of Hydro-Logic Ltd, has been appointed as a UK distributor of In-Situ's range of Water Quality sensors and Water Level loggers.

The water quality range includes the RDO Pro Optical Dissolved Oxygen sensor which requires minimal maintenance because there is no membrane to replace. The RDO Pro is one of the sensors available as standard within the Troll 9500 multi-parameter probe.

Other parameters include electrical conductivity/salinity, temperature, pH and depth level, with extended parameters also available such as turbidity, ammonia, nitrate and chloride. The Aqua Troll 100/200 models measure only conductivity/salinity, temperature and depth level.

All sensors are easily linked to Isodaq's new Frog RX GSM/GPRS logger either via 4-20mA input or via SDI-12 for multi-parameter probes. Isodaq systems are low-cost and very easy-to-use enabling key decision makers to acquire water quality information from remote sites at a fixed frequency e.g daily or hourly.

For pollution warning, intake protection or discharge consent compliance applications, Isodaq offer a range of telemetry server, alarm handling or web-site service solutions for delivering warning messages to standby staff.

To complete the range of water quality monitoring solutions for remote sites, Isodaq outstations seamlessly connect to the Aquamatic range of automatic samplers enabling a pre-defined sampling programme to be triggered when a change in quality has been detected.
