Subject: Calibration standards for benchtop pH meter
I wanted to get approval to order some Turbidity calibration standards for our HACH 2100N benchtop Turbidimeter. Part # 2662105 Price is $207.00 and Conductivity standard Part # LZW9711.99 $14.05. I will order through HACH. We are required to calibrate these instruments quarterly and these standards should last a couple years.
