Direct Soil Measurement pH Portable Meter - HI99121
$
-
The HI99121 is the perfect portable pH meter for soil testing. With the HI99121 and HI12923 direct soil pre-amplified pH and temperature probe, users can test both the pH of soil directly or after preparation of a soil slurry with deionized water. The HI12923 features a conical, rugged tip that can be directly inserted into moist or soft soil. For harder soils, the kit includes a plastic auger to perforate the ground.

Portable Waterproof pH/EC/TDS Meter (Low Range) - HI991300
$
-
The HI991300 is a slim, lightweight, and waterproof portable meter that measures pH, conductivity (EC), total dissolved solids (TDS) and temperature with a single amplified probe. The meter operation is simplified with two buttons. One is used for on/off and for calibration while the other is used to switch between the measurement modes. The HI991300 has advanced features including a selectable EC to TDS conversion factor (0.45 - 450 ppm and 1.0 - 1000 ppm).
3 in 1 amplified probe with pH, EC/TDS and temperature sensors
Quick Cal Mode to calibrate pH and EC/TDS with one solution
EC to TDS Conversion factor selectable between 0.45 and 1.0
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.
Plating pH Portable Meter - HI99131
