I-1000 pH Double Junction Meter
The CHEMetrics pH Double Junction Meter, catalogue number I-1000, is a portable, waterproof pH meter able to measure pH values between -1.00 and 15.00 pH units. Features automatic temperature compensation and manual pH calibration and calibration reset functions. Also features a hold function to allow the pH meter to be removed from the solution without the reading on the display changing for ease of recording. Chemical-resistant Valox sensor housing and clog-resistant Kynar junction. Automatic shut down when not in use. Up to 500 hours battery life. Large, clear dual LCD display showing both pH and temperature. Easy user double junction electrode replacement. Comes in a convenient hard plastic carrying case, plastic lanyard and batteries.
Simply turn the meter on. Remove the protective cap from the tip of the probe. Dip the probe into the sample and stir the sample gently with the probe until the display stabilises. Calibration should be performed regularly (up to 3 pH points supported), typically everyday that the meter is used.
Instruments are manufactured and guaranteed by Oakton Instruments, Inc. 1 year warranty (6 months on electrode).

|I-1000 pH Double Junction Meter User Manual|
The measurement of pH is one of the most frequently performed water quality determinations. Water softening, precipitation, disinfection, and corrosion control are some of the many operations that depend on the careful measurement and control of pH. CHEMetrics' pH meter is applicable to the monitoring of drinking water, natural water supplies, boiler waters, make-up waters, condensate returns, swimming pools, aquariums, wastewaters, and similar samples. CHEMetrics' double-junction pH meter was specifically developed for water conditioning and purification applications. The Specified Concentration or Value (SCV) for pH in drinking water supplies in UK and Ireland is 6.5 - 9.5 to protect metallic pipes and fittings from corrosion.
pH is a scale used to define the acidity or basicity of a water-based solution. Pure water at a room temperature of 25°C is neither acidic or basic and is pH 7. Acidic solutions have a pH lower than 7, and basic solutions have a pH greater than 7. The neutral value of pH decreases as temperature increases. pH is based on a logarithmic scale, and acidity decreases by a factor of ten with the increase of a single pH unit. pH can be lower than 0 and higher than 14 for very concentrated, strong acids and alkaline solutions respectively.
