Soil and Water Portable pH and Temperature Meter
Product Features by Hanna Instruments
- Portable, waterproof pH and temperature meter for soil and water
- Automatic one- or two-point calibration for ease of use
- Automatic temperature compensation (ATC) to reduce additional calculations
- Battery error protection system (BEPS) to help prevent inaccurate readings
- Hold function to freeze display and record results
To begin with, The HI 99121N (Hanna Instruments) is a portable, waterproof pH and temperature meter that comes with the HI 1292D pH electrode for measuring diluted soil samples or soil directly, and features a large LCD screen, automatic temperature compensation (ATC), a hold function to freeze and record results, and a battery error protection system (BEPS) to reduce inaccurate readings. In addition, the meter comes with the HI 1292D electrode, which has a sturdy conical tip that you can directly insert in soft soil, and the HI 721319 plastic soil auger for perforating harder soil.
Moreover, the meter features on-screen tutorial messages to assist with calibration, which is automatic at one or two points. At this point, the HI 99121N comes with (3) AAA 1.5 V batteries that provide approximately 1200 hours of continuous use (an auto off function shuts the meter off after 8 minutes of non-use). In addition 100 mL beaker and starter buffer, cleaning and soil preparation sachets are included.
First, pH range is -2.00 to 16.00 (+ or – 0.02pH) with a resolution of 0.01 pH. Second, temperature range is – 5.0 to 105.0 degrees C (23.0 to 221.0 degrees F) + or – 0.5 degrees C (up to 60 degrees C), + or – 1 degree C (outside); + or – 1.0 degree F (up to 140 degrees F), + or – 2 degrees F (outside), with a resolution of 0.1 degrees C or F. Presently dimensions are 152 x 58 x 30 mm (6.0 x 2.3 x 1.2”), with weight 205g (7.2 oz.).
Above all, pH testers measure the acidity or alkalinity of a substance. For instance, usually researchers, manufacturers, and hobbyists use it.
In fact, Hanna Instruments manufactures a wide variety of analytical instrumentation, including pH meters, multi-parameter meters, electrodes, chemical reagents and buffer solutions. Furthermore, founded in 1978, Hanna is headquartered in Woonsocket, RI, with subsidiaries located in 32 countries. As a result, Hanna Instruments holds many firsts in the field of analytical instrumentation, including the world’s first pH electrode with a built in temperature sensor, electronic pocket-sized pH tester, and replaceable electrode pH pocket tester. Finally, in order to assure the quality of its products, Hanna is a vertically integrated manufacturer and does not subcontract any part of its manufacturing.
