HI99171

Description

The Hanna Instruments HI99171 is a durable, waterproof, and portable pH and temperature meter designed specifically for leather and paper analysis. Automatic calibration is performed at one or two points with two sets of buffers. All calibration and measurement readings are automatically compensated for temperature variations. The HI99171 uses the HI1414D glass body, amplified pH electrode that offers numerous features that improve pH testing for surface measurements. The split-level LCD displays both pH and temperature readings, along with indicators for reading stability, battery percentage, and calibration instructions.

• Automatic Temperature Compensation
• Automatic Two-Point Calibration
• Waterproof

The HI99171 uses the HI1414D amplified pH electrode with glass body. This specialized electrode offers numerous features that improve surface pH testing. An integrated temperature sensor allows for temperature compensated pH measurements without the need for a separate temperature probe. The probe’s flat sensing tip provides optimal surface contact with samples.

An integral part of any pH electrode is the reference junction. The reference junction is a part of the electrode that allows for the flow of ions located in the reference cell into the sample being tested. It is vital that this flow occurs in order to complete an electrical circuit, which ultimately determines the pH value. Poor contact between the junction and sample will prevent completion of the circuit, resulting in readings that are erratic or constantly drifting.

The flat tip of the HI1414D provides optimal surface contact between the sample and the junction. The HI1414D features an open junction design which utilizes a viscolene reference electrolyte that comes into direct contact with the sample, providing accurate, stable readings.
