What are the features of the chemtrol PC2100?

The CHEMTROL® PC2100 is a simple and reliable programmable controllers that features automatic maintenance of water chemistry, pH and ORP (Optional: Free Chlorine sensor with direct reading in PPM or mg/l) with acid or base feed, programmable super-chlorination and chemicals savings cycles and display of the Langelier Saturation Index.

What should I use to clean a pH meter probe?

Dab the end of the probe dry with a chem wipe after you rinse it. Make a 4% solution of water and sodium hydroxide for acidic coatings. To make a 250 millilitres (8.5 fl oz) solution, combine 10 grams (0.35 oz) of sodium hydroxide with 250 millilitres (8.5 fl oz) of warm tap water.

What is the pH of a chemical controller?

A chemical controller monitors the pH of the water with an electronic sensor consisting of a glass pH electrode. The pH sensor readings vary from 0 mV for a neutral pH of 7 to about -60 mV for a pH of 8. For the recommended pH of 7.4, the reading is about -25 mV.

How many chemtrol controllers are in the world?

With 100,000+ CHEMTROL® controllers installed worldwide, our technology is proven, reliable and engineered to operate flawlessly 24/7/365, giving you CLEAN water and 100% peace of mind.

What do you need to know about chemtrol 250?

CHEMTROL® 250 is a microprocessor-based digital controller designed to maintain both sanitizer ORP (oxidation-reduction potential or Redox) and water pH in Residential Pools and Spas, Commercial Pools and Spas, Hotels, Motels, Health Clubs, Apartments Buildings, Condo associations and Industrial Water Treatment.

How does the chemtrol ORP / pH digital controller work?

The CHEMTROL® 250 ORP/pH Digital Controller automatically maintains both sanitizer ORP (oxidation-reduction potential or Redox) and water pH in pools and spas. To select a function, simply press ORP or pH and then the desired function. The display shows the current function value. Use the UP or DOWN arrows to adjust to the desired value.

What’s the best way to clean pH electrodes?

NOTE: Electrodes should not be stored for a period longer than six months. Electrode stock should be rotated accordingly. General Cleaning: Soak the electrode in 1:10 dilution of household laundry bleach in a 0.1 to 0.5% liquid detergent solution in hot water with vigorous stirring for 15 minutes.
