100% pure digital communications means reliable operation even in noisy process environments. No degradation in signal even with very long cable runs up to max of 610 meters (2,000 feet) Bridging connections & modifying installations is easy and done without loss of signal quality with NEMA 6P & IP67 quick disconnect waterproof and corrosion-resistant snap connectors. No screwdrivers are ever needed. HiQ4F Female & HiQ4M Male connector set is keyed so that improper wiring is not possible to avoid damage to sensor and/or transmitter. Low-cost snap digital extension cables facilitate consolidation of transmitters into a single panel enclosure where very many remote field installations can all be conveniently all viewed at once. Smart 3TX-HiQ software identifies the type of sensor connected to confirm it is compatible for the mating transmitter. There exists no possibility of ever interfacing the wrong sensor type. 3TX-HiQ-pH smart configuration feature automatically recognizes & differentiates between pH & ORP ...

Manufacturer: Hanna Instruments Brand: Hanna Instruments Model: HI98121

The HI 98121 pH/ORP/Temperature Tester is a waterproof combination pocket pH, Oxidation Reduction Potential (ORP), and temperature tester with a replaceable electrode and a non-clogging, replenishable fiber junction. The meter features a large LCD screen for readability, an ergonomically designed waterproof casing, and automatic temperature compensation to eliminate the need for additional calculations. It has a replaceable electrode and renewable reference junction, which helps prolong the life of the tester. The HI 98121 tester functions in temperatures of -5.0 to 60.0 degrees C/23.0 to 140.0 degrees F (+ or - 0.1 degrees C / 0.1 degrees F), and has a range of -2.00 to 16.00 pH (+ or - 0.05) with a resolution of 0.01 pH. The meter can be calibrated at one or two points for pH with auto-buffer recognition, and against five memorized buffer values. For ORP (Oxidation Reduction Potential) readings, the tester has a range of + or - 1000mV (+ or - 2) with a resolution of 1mV and automatic factory set calibra...

Manufacturer: YSI Brand: YSI

The YSI 605377 100-1 is a pH and temperature sensor for the YSI pH100 meter and has Automatic Temperature Compensation (ATC) and a 1m (3.3') waterproof cable. A pH electrode is commonly attached to a pH meter to measure the pH of a substance such as water, food, beer, or wine in lab, industrial, and food applications. This electrode provides ATC with an internal thermometer sensor for accurate readings in fluctuating temperatures. The meter comes with a 1m (3.3') waterproof cable for immersion in liquids.SpecificationspH range-2 to 16ATC temperature range-10 to 120 degrees C (14 to 248 degrees F) Operating temperature0 to 50 degrees C (32 to 122 degrees F)An electrode, also called a sensor or probe, is an instrument used with a meter to test and measure parameters of a substance. All electrodes are probes or sensors, but not all probes are electrodes or sensors. Probes, such as temperature probes, are used to penetrate a material for measurement. Common electrode types are pH, total dissolved solid (TDS), and...

Manufacturer: Jensen Distributing - Lawn & Garden Brand: Milwaukee Model: AG900

The Milwaukee AG900 is a complete testing kit that includes all you need to produce accurate reading for 3 of th most important levels in your plant production. pH, EC (Electrical Conductivity) and TDS (Total Dissolved Solids). Each of these factors can be very important to your plants and their chance to survive and thrive. The AG900 includes an SM802 Hand-held microprocessor, a measuring cup (used for testing soil), calibration solution, protective carrying case, 9V battery and an In-Depth manual that explains how to successfully operate your testing kit. The SM802, with a conductivity range that goes up to 6.00 mS/cm and the TDS up to 4000 ppm is ideal for testing in crop production. Soil and well water pH that is too acidic or alkaline can have an adverse effect on plant nutrient and water uptake and directly affect the efficiency of fertilizer, herbicides and pesticides. Soil Conductivity is checked before fertilizer application to pinpoint field needs and after fertilization to establish its effectivene...
