Product Description

The HI 99121N 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. The meter comes with the HI 1292D electrode, which has a sturdy conical tip that can be directly inserted in soft soil, and the HI 721319 plastic soil auger for perforating harder soil.

The meter features on-screen tutorial messages to assist with calibration, which is automatic at one or two points. 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). A 100 mL beaker and starter buffer, cleaning and soil preparation sachets are included.

pH range is -2.00 to 16.00 (+ or - 0.02pH) with a resolution of 0.01 pH. 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. Dimensions are 152 x 58 x 30 mm (6.0 x 2.3 x 1.2”), with weight 205g (7.2 oz.).

I purchased one these HI 99121 meters a few years ago and I don't know how I survived without it! I mean you literally just stick the probe in the soil and you get a instant pH reading. I used to never check my soil pH simply because it was too time consuming, but now I check my soil every week. And its fun to use. Worth every penny! It is also very accurate. I compared it with university tests for the same soil and it was the same. I just had to share this with someone.

Enjoy!
