Accessories & Standards
Keep your Hanna Checker running in top shape with genuine replacement reagents and standards. Hanna Instruments standards are made to test your checkers with known values that will allow you to offset your reading or compensate for a range of error, and in some cases you can even calibrate your checker to the correct value for more accurate readings.
