The most time consuming part of carrying out a microbial count is the actual counting process on petri-dishes. Digital Colony Counter is designed for quick and accurate counting of bacterial and mould colonies in petri dishes. Feature packed and easy to use, this is an indispensable bench top tool for the busy microbiologist.
It is designed for rapid and accurate counting of bacterial and mould colonies. Simply place the petri dish on the illuminated pad and touch the dish with the pen provided to mark each colony in turn. This causes a count to be registered on the digital display and an audible tone confirms each count made. Marking the dish with the pen avoids missing colonies or double counting. The digital count on the display can be reset manually any time by pressing reset key provided.
Optimum viewing of colonies is aided by peripheral glare free illumination graticuled disc provided in the instrument. The magnifier magnifies the colony area. This is an indispensable tool for the microbiologist.

  • PH Meter – Pen Type

Pen Type pH Meter -   is a low cost pH Meter with automatic temperature compensation. As an optional extra, you can select to purchase the pH buffer solution.

  • 0-14pH Measurement Range
  • 0.01 Resolution

TDS Meter – Pen Type

 TDS Meter indicates the Total Dissolved Solids (TDS) of a solution, i.e. the concentration of dissolved solids in it. Since dissolved ionized solids such as salts and minerals increase the conductivity of a solution, a TDS meter measures the conductivity of the solution and estimates the TDS from that.
Dissolved organic solids such as sugar and microscopic solid particles such as colloids, do not significantly affect the conductivity of a solution so a TDS meter does not include them in its reading.
