HI98129

Description

The low range Combo^® pH, EC, TDS (ppm) and temperature meter is one of Hanna’s most popular meters. The waterproof design, simple operation, and replaceable electrode mean that you can rely on this meter for years. The HI98129 is designed for low range use (0 to 3999 µS/cm or 0-2000 ppm). Choose the HI98130 for the high range model.

•  Compact & waterproof design fits right in your pocket so you can take it anywhere.
•  Great for hydroponics, aquariums, pools, & ponds.
•  Replaceable pH electrode extends the life of your tester for years.

The HI98129 is an easy-to-use and accurate waterproof pH, conductivity, TDS (ppm) tester. It measures pH, EC in the low range (0 to 3999 µS/cm), TDS (0 to 2000 ppm), and temperature. This floating, waterproof combination pocket tester has an easy to read, LCD and an automatic shut-off. All pH, EC, and TDS (ppm) readings are automatically temperature compensated (ATC) to prevent temperature-related variations in your measurements. For EC and TDS (ppm) readings, the EC/TDS conversion factor (CONV) is selectable by the user, as well as the temperature compensation coefficient β (BETA).

High Accuracy EC and TDS (ppm) Tester Probe
•  The graphite conductivity probe provides greater accuracy because it cannot be contaminated by salt deposits in the solution.
•  The exposed temperature sensor provides fast response times and guarantees highly accurate temperature compensated readings.

Replaceable pH Electrode Cartridge
•  The HI98129 tester features an easy to replace pH electrode cartridge with an extendable cloth junction.
•  The extendable cloth junction helps increase electrode life and the replaceable pH cartridge means that this tester does not need to be thrown away when the pH
sensor is exhausted. Also, the sturdy, snap-in connector means there are no pins to bend or break!

  Features at-a-glance
3 sensors in a single meter
•  Amperometric EC/TDS sensor
•  Exposed temperature probe for faster EC and TDS (ppm) readings
•  pH electrode with extractable junction

  Auto-off
•  Auto-off  feature automatically shuts off  meter after 8 minutes of non-use to maximize battery life

  Automatic Temperature Compensation
•  All readings are compensated for variations in temperature Temperature displayed in ^oC or ^oF along with pH, EC or TDS reading

  BEPS (Battery Error Prevention System)
•  Meter will automatically shut off if there is not enough power to get an accurate measurement

  HOLD button
•  Freezes reading on the display to allow recording of measurement

  Stability indicator
•  Meter displays a clock tag that will disappear when the reading has achieved stability

  Selectable EC to TDS (ppm) conversion factor
•  Choice of either a 0.45 or 1.0 conversion factor

  Low Battery Indicator
•  When the level is below 5%, the  battery symbol on the LCD blinks to indicate a low battery condition.

  Waterproof
•  Designed to float if accidently dropped in sample

  Wide pH Range
•  pH range is from 0.00 to 14.00 pH
