We have often been asked to provide water analysis testing. This year we have added some new products from CHEMetrics. CHEMetrics was founded in 1969 by Gordon Rampy, principal and CEO, to exploit his development of a unique device for conducting colorimetric water analysis. Their extensive product line of water and wastewater testing kits is based on Rampy's invention of a self-filling reagent ampoule. This innovative technique has greatly increased the simplicity, convenience, speed, and safety of colorimetric water testing, both on-site and in the laboratory. Their products have always provided faster, simpler, safer solutions for water analysis. CHEMetrics delivers high quality and dependable products - ideal for today's lab.
Oxygen (dissolved) Kit. CHEMetrics is the worldwide leader in colorimetric, low-level Dissolved Oxygen analysis. We are pleased to offer the Dissolved Oxygen Kit. This product is used frequently in environmental education to monitor local surface waters as well as classroom use by the student(s). Order No. 90-7512 1-12 ppm $45.10 (each)	Hardness (Total) Water Kit. The EDTA titration method measures the calcium and magnesium ions and may be applied with appropriate modification to any kind of water. This procedure affords a means of rapid analysis. The total hardness method is applicable to drinking, surface, boiler, and brine waters. If no magnesium is present, the end point of the titration normally appears sluggish. However, the reagent has been specially formulated to ensure a sharp end point regardless of the presence of magnesium.
