The Hanna Instruments HI99181 is a durable, waterproof, and portable pH and temperature meter designed specifically for analysis of skin. 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 HI99181 uses the HI14143/50 amplified pH electrode with glass body that offers numerous features that improve pH testing for skin and surface measurements. The split-level LCD displays both pH and temperature readings, along with indicators for reading stability, battery percentage, and calibration instructions.
Features:
- Waterproof - The HI99181 is a waterproof meter rated IP67 for immersion in up to one meter of water for 30 minutes.
- Automatic Calibration - One or two-point calibration is automatic to two selectable buffer sets.
- Automatic Temperature Compensation An integrated temperature sensor allows for automatic temperature compensation of pH measurements.
- Sensor Check - Using the pHmV range the user can check the sensor status by reading the mV reading in fresh buffers. At room temperature (25 oC/77oF) the reading should be +/- 30 mV in pH 7.01 and greater than 150 mV difference between pH 7.01 and 4.01.
- Multi-Level LCD Display - The split-level LCD displays both pH and temperature readings, along with indicators for reading stability, battery percentage, and probe condition.
- Probe Condition Indicator - The probe condition indicator is based on the offset and slope characteristic of the electrode. There are 5 bars ranging from all 5 indicating the probe is in excellent condition and 1 bar indicating the probe should be cleaned or replaced.
- Battery Error Prevention System - The meter will automatically shut off if there isnt enough power to obtain an accurate measurement.
- Battery Life Indicator - The battery percent level is displayed at start up alerting the user to the remaining battery power that is available.
Probe features:
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 HI14143/50 provides optimal surface contact between the sample and the junction. The HI14143/50 features an open junction design which utilizes a viscolene reference electrolyte that comes into direct contact with skins surface, providing accurate, stable readings.
- Glass Body: The glass body of the HI14143/50 is chemically resistant and quick to reach thermal equilibrium, allowing for a faster, more stable response.
- Flat Tip: The flat tip sensing bulb allows for the direct surface measurement of skin. Maximum surface contact is achieved with this specialized tip shape.
- Open Junction Reference: The open junction design consists of a solid gel interface (viscolene) between the sample and internal Ag/AgCl reference. This interface not only prevents silver from entering the sample, but also makes it impermeable to clogging, resulting in a fast response and stable reading.
- Built-in Temperature Sensor: Errors in calibration and measurement are eliminated with the Automatic Temperature Compensation provided by the integrated temperature sensor.
