The patented pH-Fix technology stands for a high quality, color-fixed pH test strip system. For many years chemists as well as inexperienced users have appreciated pH-Fix's optimal usability, reliability, and precision. The long handle prevents fingers from coming into contact with the sample. It adds handling convenience and increases safety of operation. This allows a high standard of "workplace safety" when testing aggressive solutions. To prevent bleeding, the pH-indicator is chemically bound to the cellulose fiber. Unlike classic pH papers, pH-Fix effectively protects the sample against contamination and enables measurements even in weakly buffered or strongly alkaline solutions. Four different color blocks for each pH-value (pH-Fix 0-14) ensure highly precise pH-determination and make the application rapid and reliable.

This is a highly accurate pen-type PH meter for you to measure PH levels of liquids quickly and conveniently. This PH meter is reliable, portable, sensitive and able to give a quick response of PH. The backlight LCD equipped enables users to do testing and measurement even in dark fields. Since PH value varies with temperature, this PH meter is equipped with Automatic Temperature Compensation (ATC), so you don't need to worry about the effect of temperature change on PH level. PH value will be automatically adjusted in temperature between 32 - 122 °F (0 - 50 °C). This PH meter is very useful to test PH level of liquids for various industries and applications such as water sources, environmental monitoring, laboratories, hydroponics, aquariums, swimming pools, spas and food processing etc. Specifications pH measuring range : 0.00 - 14.00 PH Resolution : 0.01 PH Accuracy : ±0.1 PH Backlight LCD Display for working at low lighting environment Automatic Temperature Compensation : 32 - 122 °F (0 - 50 °C). Operating Temperature : 32 - 122 °F(0 - 50 °C) Power: 4 x 1.5 V (AG-13) button cell batteries (Installed) Dimensions : approx. 5.90' x 1.06' x 0.79' inch (151 x 33 x 20 mm) Weight : approx. 1.88ounce (53g) One set included 1 x Pen-type pH meter 2 bags each of pH 4.01 and pH 6.86 Calibration Buffer Powder 4pcs x AG13 button cell batteries (installed) 4pcs x AG13 button cell batteries (packed separately) 1 x Instruction Manual 1 x Portable storage case

Potassium iodate starch paper is a filter paper impregnated with potassium iodate (KIO 3 ) and starch, which is used for the detection of sulphurous acid (H 2 SO 3 ) and alkali sulphites. The stoichiometry of the reaction is as follows:2 IO 3 û + 5 SO 3 2û + 2 H + « 5 SO 4 2û + I 2 + H 2 OThe sulphurous acid reduces potassium iodate to form elemental iodine which reacts with the starch in known manner to a blue-violet complex. Thus the white potassium iodate starch paper turns blue-violet in the presence of H 2 SO 3 .Limit of sensitivity: 5 mg/l SO 2Recommended application: detection of sulphur dioxide (SO 2 ) in the chemical laboratory, testing of meat products suspected of containing added sulphite.Note: For the detection of sulphite in meat products, also refer to our Sulphite test paper.
