Single-use standards eliminate concern about external container contamination. Calibration is made in the standard’s vial. Fits all probes. Extra-large opening (1-3/4 inches diameter) and extra-large, 3-1/2 inches depth allow probe calibration to take place in the standard’s polyethylene container. Ideal for lab or field conditions. Accuracy at 25°C is ±0.25 micromhos for 5 and 10 solutions and ±0.25% for all other solutions or the uncertainty shown on the certificate, whichever is greater. Compatible with all makes of equipment. Each bottle is labeled for calibrating conductivity, resistivity, and dissolved solids (parts per million). Supplied with individual serial numbered Traceable® Certificate, Certificate of Analysis, and step-by-step calibration instructions. Supplied as a pack of six. Each standard contains 100 mL.
