pH 4.01 Calibration Buffer Packets for pH Meters
The Milwaukee 4.01pH Buffer 20ml Calibration Case (25) is a case of sealed pH 4.01 calibration packets for pH meters, testers, probes, monitors, and controllers. Each packet contains ready-to-use buffer solution, so there is no powder mixing or shared bottle to manage.
Use this buffer when a pH meter requires a 4.01 calibration point. The solution is rated at ±0.01 pH accuracy and comes in sealed 20mL packets that help reduce air, light, and storage errors before use.
Key Features:
- pH 4.01 calibration buffer solution for pH meters and probes.
- Sealed 20mL packet format for fresh calibration solution.
- Standard ±0.01 pH accuracy for repeatable calibration.
- Ready-to-use liquid avoids powder mixing.

Instructions:
- Open one sealed 20mL packet when ready to calibrate.
- Rinse the pH probe or tester tip with clean water before calibration.
- Insert the tester or probe into the 4.01pH buffer packet.
- Wait for the reading to stabilize.
- Complete the calibration step according to the meter, monitor, or controller instructions.
- Rinse the probe after calibration before placing it into another buffer or back into the aquarium system.
- Discard used buffer after calibration. Do not reuse used solution.
- Store unopened packets away from heat and direct light.
