Infrared IR Digital ThermometerNon-contact accurate temperature measuring Bulit in Laser aiming Review
Operating Instructions:
1. Open cover of battery, install 9V battery, and select the switch of aiming laser and ?/? switch at a proper place as your needs, and then close the cover of battery.
2. Point the aiming sensor at an object (Be sure to consider distance-to-spot ration and field of view), and push the testing switch , and the temperature reading will appear on the display. When the testing switch is released, the LCD will auto-store the last temperature reading and turn off in about 15 seconds.
3. Pressing the Scan Trigger again will restart the testing process.
4. Please replace a new battery when battery symbol displayed on left of LCD.
Remind:
Do not point the laser directly at the eyes of any people or animal.

Hanna Instruments HI 98121 Combination pH/ORP/Temperature Tester Review
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 calibration. Dimensions are 163 x 40 x 26 mm (6.4 x 1.6 x 1.0"), with weight 100 g (3.5 oz.).
pH testers measure the acidity or alkalinity of a substance and are commonly used by researchers, manufacturers, and hobbyists.

Oakton EcoTestr pH 2 Waterproof pH Tester, -1.0 to 15.0 pH Range Review
The Oakton 35423-10 EcoTestr pH 2 is a handheld, waterproof, and dustproof pocket meter that measures pH and floats, if dropped in liquid. A portable pocket meter is commonly used to measure the pH of substance in hydroponics, education, water treatment, and swimming pools. This meter has ATC for accurate readings in fluctuating temperatures, and push-button calibration capabilities up to three points for a wide range of results. It features a transparent, protective cap to reduce contamination and protect the sensor. The cap keeps the sensor moist when stored upright, and can be used as a container for sensor-conditioning, or on-site calibration. The meter’s waterproof and dustproof housing has IP67-rating for protection against solid objects or liquids. The testr has a long-lasting sensor with Polyvinylidene Fluoride (PVDF) reference junction with polymer gel for long lifespan. The meter has a large, upright, single-line LCD screen for ease of viewing, a hold function which freezes readings for recording, and an auto shut-off to extend the life of the batteries. It has a click-lock battery cover for battery access to replace batteries without tools.
The 35423-10 pocket meter comes with an integral sensor, has ATC from 0 to 50 degrees C (32 to 122 degrees F), and works in an operating temperature of 0 to 50 degrees C (32 to 122 degrees F). It has three-point automatic calibration at three US buffer values of US 4.0, 7.0 or 10.0. pH range is 0.0 to 14.0, resolution 0.1, accuracy + or - 0.1. Its dimensions are 1.25 (l) x 1.5 (w) x 6.5 (h) inches (3.2 x 3.8 x 16.8 cm) and it weighs 3.25 ounces. The testr works with four 1.5-V alkaline batteries (not included) for up to 250 hours of continuous use (Eveready A76 or LR44 replacements).
pH testers measure the acidity or alkalinity of a substance and are commonly used by researchers, manufacturers, and hobbyists in aquaculture, agriculture, hydroponics, wine-making, and water-testing, and for scientific applications.
