Thiết bị đo độ tinh khiết khí CO2 trong bao bì, gói Zahm & Nagel PART #10007 CO² PURITY TESTER 50-100% IN 1.0%


The Purity Tester consists of a caustic reservoir and calibrated absorption burette mounted to a PVC polished frame. The reservoir and burette are held to the frame with two neoprene covered mounting bands that are adjustable from the rear side of the frame. The absorption burettes are available in five different calibrations, with the standard burette graduated in tenths of one percent, the total being one percent of the volume of the burette. The caustic reservoir (10100) has a line indicating the level to which caustic solution should be added, which volume is slightly in excess of the capacity of the absorption burette. The line drawings should be used for identification of the Purity Tester parts. When inquiring about our gas purity testers, please specify which absorption burette you require.

Operating Instructions:

Caution: Caustic solution is used in the operation of this instrument. This solution may cause severe burns to the operator if not handled with care. Wear goggles and protective clothing while operating this instrument.

Preparation of Caustic Solution:

A 20% solution of either Potassium Hydroxide or Sodium Hydroxide is recommended for air testing*. To make a 20% solution slowly add 100 grams of Potassium or Sodium Hydroxide crystals to 500 cc’s of distilled water and store in a sealed jar. The Hydroxide solution may also be purchased from any laboratory or chemical supply company. *A weaker solution may be used, but the tests will take longer and fewer tests can be performed.
