Aquaculture operators in search of a better way to automate testing for DO, pH, ammonia and other parameters will find the modular plug-n-play T80-S80 Analyser System from Electro-Chemical Devices (ECD) simplifies operations and lowers total operating costs.

In aquaculture, the reliable detection of levels of dissolved oxygen (DO), pH, ammonia and other parameters is essential to keep fish healthy.

These parameters can reach toxic levels quickly, or facilitate conditions that lead to disease affecting the health of fish, which requires additional treatments or can cause the death of the fish.

Many operators rely on portable sensors, which require staff time to manually complete the testing on a fixed schedule. This can be hard to maintain consistently during a busy work day.

The challenge and expense of dedicating staff time to testing becomes incrementally problematic in larger or remote operations.

The installation of fixed analyser systems, such as the rack-mount ECD T80 Universal Transmitter with S80 Intelligent Sensors, automates the measurement process.

The T80-S80 Analyser System can be seamlessly integrated with popular control system communication protocols to provide a closed-loop water monitoring and treatment system that maintains water quality for optimum fish growing conditions.

The T80 Transmitter’s own highly intelligent digital protocol simplifies installation set-up and process measurements while also reducing maintenance costs.

The single and two-channel models offer membrane switch navigation, a simple menu structure and soft key menu choices with an easy-to-read 2.75 x 1.5inch LCD display.

The T80 transmitter is available in three different power modes – a loop-powered transmitter, a 24 VDC line-powered or a 110/220 VAC line-powered transmitter.

The line-powered instruments have one or two 4-20 mA outputs with MODBUS RTU and optional alarm relays.

The T80 can be configured with optional HART® 7 communication protocol.

The T80 Transmitter digitally communicates with any S80 Sensor, automatically uploading the sensor’s calibration data and configuring the transmitter’s menus and display screens to the desired parameter.

S80 Sensors feature a choice of two universal sensor designs: insertion/submersion or valve retractable with flared end to prevent blow out.

They have a rugged 0.75-inch OD 316 stainless steel body with a 10-foot cable or an optional waterproof detachable cable assembly.

The versatile DO80 DO Sensor features a measurement range from 0.00-20.00ppm (mg/l) over a temperature range from -10° to 60°C. For pH, the S80 features a measurement range from 0.00 -14.00pH with a temperature range of -10° to 90°C. To monitor ammonia requires a two channel instrument, pH and NH 3 .

The S80 NH 3 Sensor has a measurement range of 0.1ppm to 17,000ppm NH 3 over a temperature range from 0° to 40°C.

With the S80 Sensors, the economical auto clean option includes a solenoid actuated spray cleaner using either 30 psi process water or air. An easily adjusted timer controls the period and duration of the cleaning cycle.

The auto clean option pays for itself by reducing time-consuming manual maintenance routines, which frees staff for other more productive activities.

Combining ease of set-up, modular design and low maintenance, the T80-S80 Analyser System is ideal for demanding aquaculture applications.

From single point of measurement to monitoring multiple parameters, the flexible T80-S80 Analyser System is an economical automation tool for effective aquaculture production operations.
