Turbidity is the measurement of suspended or undissolved partials present in a liquid, our instruments measure in NTUs (Nephelometric Turbidity Units) the measurement principal is based on how light is scattered or reflected by these partials. Please note turbidity is a measurement of the clarity of a solution not colour, water with a cloudy appearance will have a higher turbidity than a clear red wine.
Applications include measurement of potable waters from water treatment plants, swimming pool waters, to discharge from industrial effluent treatment plants to verify the settlement process is effective.
TU7685 Turbidity meter based on the Nephelometric method of measurement auto or manual range selection form 0 - 4.00, 0 - 40.00, 0 - 400.0 or 0 - 4000. NTU with two control relays one alarm relay and an isolated current output. The TU7685 is for use with the TU800 Infrared light sensor which carries out the measurement. The sensor maybe mounted up to 100 metres away from the TU7685 Turbidity meter.
-W W’proof enclosure to hold 1 or 2 7600 instruments (add)
Sensors are available as follows
TU800 -F Off line flow cell in PVC for a small flowing sample of 0.25 to 25 litres/min, connection by 8 mm OD tubing max temperature 30°C.
TU800 -D Dip sensor 600mm long with PVC riser tube and mounting flange.
TU910 10 metre long connecting cable with wproof connectors
-AC Dip sensors can be supplied with an auto clean compressed air sensor cleaning system comprising of a small 240 volt air compressor solenoid and regulating valves with air blast nozzle includes option auto clean function in the instrument.
TN100IR Microprocessor based portable Turbidity meter uses an infrared LED light source to provide laboratory standard repeatability and accuracy. Measurement range 0 - 1000 NTU units in 3 ranges automatically selected from 0 -19.99, 0 - 99.9 and 0 - 1000 NTU. Supplied with sturdy compact carrying case, calibration standards and sample vials.
The waterproof pH Tester model:- pHTestr10 has a simple push button 3 point calibration mode. This reduces the time needed to buffer the unit to allow for the quick measurement of pH values. By using the a 3 point calibration the pHTestr 10 offers precision readings across the logarithmic pH scale while also being housed in an IP67 Rated Waterproof enclosure.
The calibration process is simple using pHBS4, pHBS7 and pHBS10 from our pH buffer solution range to give a representative sample across the pH scale.
Having rinsed the instrument in water (not de-ionised water) simply insert the pHTestr10 into the first buffer solution, turn the unit on and hold the calibration button down. The instrument will identify which buffer solution, adjust it's internal value accordingly, also give you the previous reading for when the unit was last calibrated. Rinse the electrode again in water and repeat the process for the remaining buffer solutions.
Accessories for the pHTestr10 and items also purchased by AWE Direct customers.
The pHWPSEN is the Replacement electrode for the pHTestr10. The pHWPSEN comprises of a double junction pH Electrode with built in Automatic Temperature Compensation.
To replace the electrode in the pHTestr10, the old electrode simply twists off the unit and the replacement pH electrode slots into place and the holding collar is tightened to secure it.
