pH Meter with Temperature Display HI 98128 Hanna waterproof pocket pH Meter type HI 98128, which is not only temperature compensated but also displays the temperature in degrees Celsius or Fahrenheit. The case is waterproof and floats. Range 0.00 to 14.00pH Resolution 0.01pH Accuracy +/-0.05pH Calibration automatic 1 or 2 point calibration Buffers pH 4.01/7.01/10.01/6.86 & 9.18 are memorised Compensation temperature compensated and displayed between 0.0 and 60.0C Dimensions 163 x 40 x 26mm; weight 85 grams It is recommended that this instrument is purchased with sachets of calibration buffer solution.   Price: £64.63 (Including VAT at 17.5%)
	Add 5 X pH4.01 and 5 X pH 7.01 Buffer solutions £8.37
	Total Dissolved Solids Meter HI98311 Hanna meter HI98311 similar to the waterproof pH/Temperature but one which measures Conductivity and Total Dissolved Solids from 0 to 2000mg/litre. A replacement sensor is available to special order. It features a dual level easy to read LCD display which shows the conductivity (or TDS) reading alongside the temperature reading. Packed with features such as adjustable TDS ratio, temperature readout in Centigrade or Fahrenheit, automatic calibration, automatic shut-off and battery life indicator, yet simple to use with only 2 fully sealed buttons. The combined conductivity/TDS sensor uses graphite modules which provide better repeatability than conventional sensors as they do not oxidise. The sensor module is replaceable and can be ordered separately as a spare or replacement. In order to allow you to check that your meter is in calibration, we supply calibration check solutions. To test your meter, simply press and hold one of the meter buttons to enter calibration mode, the meter will then automatically recognise the solution value and adjust its' own calibration to match. It is recommended that this instrument is purchased with sachets of calibration solution.  Price: £78.37 (Including VAT at 17.5%)
	Add 5 x 1382ppm TDS Calibration Solution £4.18
