TAC Alkalinity Test Pills (Alca-M) for Photometer - Box of 100 - Lovibond - Part No. 513210BT

The reference reagent for measuring total alkalinity

A quick and reliable way to check TAC to maintain perfectly balanced water.

Alca-M (Alkalinity-M) test tablets measure TAC, which is the concentration of bicarbonate ions dissolved in the water. TAC is a key indicator of water balance: proper TAC stabilizes pH, optimizes the effectiveness of disinfectants, and protects equipment from corrosion. Thanks to their tablet form, these reagents can be precisely dosed, have a long shelf life, and are safe to handle—making them the most popular indicator system and the most cost-effective solution for analyzing this parameter.

How does it work?

The principle is simple: add a tablet to the water sample, crush it using the stirring rod, wait for the color to change, then take a reading on your photometer. The colorimetric reaction is analyzed by the device, which directly displays the TAC value.

Why choose them?

• Reliable determination of TAC (total alkalinity)
• Compatible with Lovibond photometers
• Precise dosing thanks to the tablet form
• Exceptional durability: packaged in aluminum blister packs, they withstand almost any weather conditions
• Safe for the user
• Economical box of 100 tablets

Instructions for Use

Place the water sample in the measuring cell. Add one Alca-M tablet, then crush it with the stirring rod to dissolve it completely. Wait for the color to develop, then take a reading with the photometer using the Alca-M method. Refer to your device’s manual for the exact procedure.
