Total Hardness CAL Check™ Standards – HI97735-11

The HI97735-11 Total Hardness CAL Check™ standards provide a simple solution to calibrating and validating the HI97735 Total Hardness EPA Portable Photometer that features three measurement ranges. The HI97735-11 CAL Check™ standards can be used for the low (0 to 250 mg/L CaCO3), medium (200 to 500 mg/L CaCO3), and high (400 to 750 mg/L CaCO3) ranges of total hardness determination. This high quality set of standards is manufactured in our state-of-the-art facility and comes supplied with a certificate of analysis. The certificate of analysis provides the lot number, reference values, and expiration date for traceability when certifying the HI97735 photometer.

  • Supplied with Certificate of Analysis

  • Standard value of 150 ±5 (low range), 350 ±7 (medium range), 520 ±10 (high range) mg/L CaCO3 @ 25℃
  • Reusable with long shelf life stability

Digital PEI Body pH Electrode with Matching Pin for Field Applications - HI12301

481 AED
The HI12301 is a plastic body, double junction, gel filled pH electrode with a matching pin and built-in temperature sensor for temperature compensated measurements in a single probe design. This probe connects to the meter with a 3.5 mm connector. The 3.5 mm connector is proprietary to meters that use digital electrodes. The matching pin integrated into the HI12301 is for the Sensor Check™ capability of the edge pH meter; this feature is used to identify problems with the pH electrode such as cracks in the sensing glass or poor condition of the reference junction. The HI12301 electrode features a built-in microchip that stores sensor type, serial number, and calibration information. It also features a single ceramic junction and the spherical pH sensing portion is made with low temperature glass. The electrode has a rugged PEI (polyetherimide) body that has the chemical resistance of a glass body in an unbreakable plastic making it ideal for field and industrial applications.
  • Matching Pin for enabling Sensor Check feature that alerts to a broken electrode or clogged junction
  • Double Junction Reference
  • 3.5 mm Connector

HI12883 pH/EC/TDS Multiparameter Probe with Quick Connect DIN Connector

583 AED
The HI12883 is a 3-in-1 pre-amplified multiparameter probe that measures pH, EC/TDS, and temperature within a single polypropylene body. The pH portion of this probe is constructed with a cloth junction, maintenance free polymer gel electrolyte, and a low temperature glass sensing bulb. The EC/TDS portion of this probe utilizes two graphite sensors for an amperometric determination of conductivity and total dissolved solids. A built-in temperature sensor ensures that both pH and EC/TDS readings are compensated for temperature variations in both standards and samples. The design consideration for the HI12883 is ideal for measuring the pH, EC/TDS, and temperature in greenhouses, hydroponics, environmental monitoring, water treatment, wastewater treatemnt and boilers and cooling towers. The HI12883 is designed for use with Hanna’s HI991300 and HI991301 portable multiparameter meters.
  • Pre-amplified pH electrode
  • Amperometric EC/TDS sensor
  • Built-in temperature sensor
