Portable Waterproof pH/EC/TDS Meter (High Range) – HI991301

The HI991301 is designed to measure pH, conductivity (EC), total dissolved solids (TDS), and temperature with a single probe. From setup to calibration all operations are performed with just two buttons. The meter is waterproof and rated for IP 67 conditions.

The HI12883 pre-amplified multiparameter probe features an easy-to-clean sensor and a cloth junction that can be renewed to increase the life of the probe. To ensure against interference from transient electrical noise, a solid-state amplifier is integrated into the HI12883.

User-selectable features include different TDS factors from 0.45 to 1.00 and a range of temperature coefficients (β) from 0.0 to 2.4% for greater consistency and reproducibility. Standardized buffer recognition values are also selectable.

These instruments easily fit in the palm of your hand and the bottom probe connection ensures the electrode cable doesn’t get in your way. The large, multi-level LCD displays the primary reading, temperature, and calibration guides simultaneously.

HI12883 Multiparameter Probe

The HI12883 multiparameter probe includes pH, EC/TDS, and temperature measurement. A solid-state pre-amplifier is integrated into the probe to protect against interference from transient electrical noise.

Amperometric conductivity probe
Built-in temperature sensor
Easy-to-clean
The sensor is easy to clean and maintain by design
pH sensor with extendable cloth junction
The HI12883 multiparameter probe features a cloth junction that can be pulled longer, effectively increasing the life of the probe

Features at-a-glance

3 sensors in a single probe

pH electrode – Preamplified for resistance to electrical noise including that generated by pumps and ballast

EC/TDS sensor – amperometric two pole design

Temperature – NTC sensor for accurate temperature measurement and compensation

Waterproof

Designed to withstand the humidity of a growing environment

Wide pH Range

pH range is from 0.00 to 14.00 pH

Selectable EC to TDS conversion factor

Choice of either a 0.5 or 0.7 conversion factor

0.5 (500 CF) conversion factor is for an EC reading of 10 mS/cm = 5 ppt

0.7 (700 CF) conversion factor is for an EC reading of 10 mS/cm = 7 ppt

Automatic Temperature Compensation

All readings are compensated for variations in temperature

Temperature displayed in oC or oF along with pH, EC or TDS reading

Stability indicator

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

HOLD button

Freezes reading on the display to allow recording of measurement

BEPS (Battery Error Prevention System

Meter will automatically shut off if there is not enough power to get an accurate measurement

Battery % level at startup

Low Battery Indicator

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

Auto-off

User selectable automatic shut-off ff to conserve battery life. Options are after 8 minutes, 60 minutes , or disabled.
