INCREMENTS are 10mm, 20mm, 30mm, 40m, and 50mm.
INSTRUCTIONS INCLUDED for caliper calibration testing. Caliper not included.
ALUMINUM CONSTRUCTION for hardness and durability..

This digital pen instrument is an ideal instrument for any aquarium, fishery, swimming pool, school laboratory, food and beverage, etc. Moreover, this digital water quality tester is ideal for all basic water testing applications..
Due to its advanced microprocessor technology, the product is efficient and accurate..
The value of water quality inspection pen can show the impurity content. The larger the value, the greater the impurity content.
on the contrary, the less impurity content..
The factors that affect the test value are: the temperature of the water (the tester cannot test high-temperature water, such as boiled water).
the flow rate of the water (the tester cannot be used to test flowing water) Hold function: save the measurement for easy reading and recording..
Auto-off function: After 10 minutes of non-use, the meter can be turned off to save battery power..

...nductivity meter, TDS meter, Salinity meter or D.O. meter as user needed..
We design different color connector on the meter, user only needs to screw on the probe with the same color, and then get the measuring reading accurate and fast..
User could change the probe or screw on the 86031 Combo Water Quality Measuring Instrument easily. And in order to avoid broken by the stone or particle attacking in the measuring environment, we have developed the specific anti-collision cap on each probe. So the 86031 Combo Water Testing Meter would be the best tool for all professional measuring purposes, including the Aquaculture, Aqua farm, LAB, swimming pool or water treatment business, or other related industry, no matter the fresh or sea water..
AZ 86031 Combo Water Meter- pH/Conductivity/Salt/TDS/D.O was being designed and manufactured by AZ Instrument, a well experienced manufacturer for pH EC Meter..
Large LCD to display multiple parameters simultaneously: pH, Conductivity or TDS or Salinity, Dissolved oxygen, Temperature (by using different probes).
