16900 Acidity Digital Titrator test kits

Summary

Product Identification

• Product: Digital Titrator
• Model: 16900
• Manufacturer: Hach Company
• Description: A portable, precision dispensing device designed for both laboratory and on-site titrations. It features interchangeable titrant cartridges for ease of use and to prevent cross-contamination. The device is built for durability and comes with a lifetime warranty against defects, excluding abuse.

Operating Limits & Performance

• Accuracy: ±1% for most samples. Uncertainty of readings is 1 digit.
• Delivery: 800 digits/mL.
• Titration Time: Most samples require 10 to 30 turns (100 to 300 digits) of the delivery knob.
• Digit Function: Each digit (1/10 turn of the knob) delivers 0.00125 mL of titrant.

Electrical

• TitraStir Stand (Optional):
  • 19400-00: 115V
  • 19400-10: 230V

Mechanical / Hydraulic

• Weight (Digital Titrator): 132 g (less than 4 oz)
• Cartridge Volume: 13 mL
• Cartridge Weight (full): 56.75 g (2 oz)
• Cartridge Performance: Enough reagent for 50 to 100 tests, depending on sample strength. Most reagents provide 100 typical titrations.
• Delivery Knob: Precisely controls titrant flow by advancing a plunger.
