The KL-98102 is an ideal pocket tester for educational purposes.
Designed with a 0.01 pH resolution and one-point manual calibration through easy-to reach trimmers, it immediately displays pH variations to reflect the smallest change in the sample.
With only two operation buttons, it allows immediate and precise response in a concise design.
This is a rugged unit that can be used again and again. The probe is even durable enough to be used as a stirrer.
The HOLD button will freeze the display reading for your documentation requirements.
The primary use of Ammonium Sulphate is as a fertilizer for alkaline soils. In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth. The main disadvantage to the use of Ammonium Sulphate is its low nitrogen content relative to Ammonium Nitrate, which elevates transportation costs. It is also used as an agricultural spray adjuvant for water soluble insecticides, herbicides, and fungicides. There it functions to bind iron and calcium cations that are present in both well water and plant cells. It is particularly effective as an adjuvant for 2,4-D (amine), glyphosate and glufosinate herbicides.

This compact tester features a large easy-to-read LCD. Unlike other pH testers, the pH electrode can be interchanged with any pH electrode of different size and shape. This allows you to use application specific electrodes and saves the cost of a new meter when it is finally necessary to replace an exhausted electrode. The tester is fast, accurate, lightweight. Testing pH has never been easier!
