The Apera Instruments PC400 is the most economical choice for a reliable portable pH/conductivity (EC) meter. Equipped with apera’s high quality 3-in-1 pH electrode and BPA (brush-resistant Platinum black) conductivity sensor, the meter tests pH, EC, TDS, and temperature in a quick and accurate manner. Also tests ORP (oxidation-reduction potential), ORP electrode is sold separately. (Accuracy: ±0.01 pH/±0.2 percent F.S, ±1.0 percent F.S; range: 0 to 14 pH, 0 to 200 MS/cm; auto or manual temperature compensation). intelligent functions: quick & easy multi-points auto calibration. The SMART self-diagnosis helps you conduct proper calibrations and determine the condition of your probe. Fully Configurable parameter setting: solution standards, temperature unit, backlight time, auto-power off time, TDS factor, temperature coefficient, etc. The large clear LCD displays pH/EC and temperature simultaneously along with icons of stable readings and finished calibrations. Reliable structure: IP57 waterproof and Dustproof, ideal for use in harsh environments. It comes with a complete Test Kit including a meter, a pH electrode, a conductivity electrode, and 6 bottles of calibration solutions (pH 4.00, 7.00, 10.01; 1413 µs, 84 µs, 12.88 MS) in a rugged carrying case. Powered by AA batteries. The product is CE certified. Notes: this product will not give accurate or stable readings for distilled or deionized waters pH testing. This is because distilled and deionized water do not have enough ions present for the electrode to function properly. To measure distilled or deionized water’s pH, users need to use a specialized pH electrode. Do not store the probe in distilled water or deionized water because they will cause damage to the glass membrane of the pH probe. Only use distilled water for cleaning the pH probe.
