iccolo Plus pH Metermsdsarrow12Piccolo Plus pH Meter

A new Improved 0.01 pH Accuracy, Replaceable probe & Temperature Read-out

Piccolo is a revolutionary pH-meter with a 4-in-1 “Electrode + Amplifier" design. Conventional pH meters are susceptible to the weak high impedance signal which makes the electrode, connector, cable and meter delicate and vulnerable to noise, humidity and dirty environments. Piccolo has overcome these problems with a pre-amplified electrode delivering a strong signal to the meter.

Piccolo has the same precision as a lab-grade meter with a resolution and accuracy of ±0.01 pH, at a fraction of the price.


  • Easy to use: Battery operated and weighing only 100 grams.
  • Replacement Electrode: The detachable electrode has sealed electrons to protect from humid and dusty environments.
  • Automatic Temperature Compensation (ATC): A temperature sensor housed in the electrode provides ATC from 0 to 70°C (32 to 144°F)
  • Temperature Read-out: A thermometer built inside a pH meter! Accurate temperature read-out directly on LCD.

Piccolo Plus comes complete with a 4-in1 Ph electrode, pH 4 and pH 7 buffer solutions, a small calibration screwdriver in a rugged carrying case.

arrow12pH Indicator Papers – Test Papers

pH Indicator Papers – Test Papers1. pH-Fix™ Universal Indicator Sticks

In contrast to conventional indicator papers, the indicator dyes of pH-Fix sticks are substantially bound to the cellulose fibers. As a result, the possibility of the color bleeding, even in strongly basic solutions, is avoided. Furthermore, there are the following advantages:

  • Measurement of pH value is possible even in unbuffered or very weakly buffered solutions, since the sticks can be left in the solution until the final color change is completed.
  • Test samples are not contaminated by the indicator dyes.
  • Colors of the individual color fields cannot run into each other, thereby allowing for a more precise comparison with the color scale.
  • Recently developed indicator dyes guarantee a sharp differentiation between the individual pH values and a clear and easy comparison to the color scale.
  • Sample application – four different indicator papers 6x5 mm are sealed on to a plastic strip 6x85 mm. The strips are sufficiently long to avoid contact between the fingers and the test sample.

pH-Fix™ Indicator Sticks are packed in a box of 100 sticks 6 x 85 mm.

PEHANON® pH Indicator Stripsarrow122. PEHANON® pH Indicator Strips

This is a series of pH indicator papers where the indicator and color scale are combined on a single strip. They permit a fast, convenient and accurate pH value determination since they eliminate the necessity to compare color against a separate scale. This presentation also permits the pH measurement of colored solutions and suspensions, since the color of the test solution acts on the comparison scale in the same manner as on the indicator field. The PEHANON® series covers the entire pH range from 0 to 12 with one universal paper and 13 narrow ranges which overlap to permit the user utmost selectivity for the range suited to each particular need.

The indicator zone (unprinted field) is in the center of the strip, the comparison fields above and below same. The strip is submerged in the solution for about three seconds so that all colors zone are wetted whereby the center field changes color according to the pH value of the solution and is then compared against the color filed bearing the corresponding pH value imprint. An invisible hydrophobic barrier just above the top color field prevents capillary action of the test solution beyond that point and corrosive, toxic or otherwise noxious liquids to not come in contact with fingers which remain clean and dry.

Strips are packed in a plastic box, containing 200 strips.

Perfect for use in fume hoods, environmental studies, or for air flow check. A highly accurate, hand-held unit, only 3 ozs. Allows you to select readout in knots, feet per minute, meters per second, or miles per hour. To insure maximum sensitivity and accuracy, the turbine is suspended on saphire jewel bearings, and its rotation is sensed by an infrared light beam, which adds no friction. The resulting signal is pro-cessed electrically by an LSI (Large Scale Integrated) circuit.

Powered by 3 "AAA" batteries included.

arrow12Denominator Laboratory Counters

There are many possible ways to count – from hash marks in the sand, to highly sophisticated computer programs.

For over 100 years, customers have relied on Denominator counters to simplify counting in a wide range of applications. Wherever and whenever you need to take a quick, accurate count, the durable, long-lasting, ergonomic and easy to use Denominator is the perfect solution for fast, accurate tallies.

Rugged and reliable, Denominator Tally Counters are appropriate for many Quality Control applications. Counts of rejections can be made by designated categories, either in process or at final inspection.

Customers rely on our Denominators for Traffic surveys. The counters are available in any configuration to meet your needs. They may be single- or multiple-mounted vertically or horizontally. Portable counters may be mounted on hand-held clipboards. Our Denominators are rugged for long and dependable service, yet compact and lightweight.

Denominators are used in a wide range of laboratory applications, including Hematology, Botany, Geology, Entomology, Oceanography and other medical and scientific laboratory settings. The counters may be banked or tiered, and various mounting options are available to suit your needs.

Totalizers are available for use in situations where a cumulative line total of individual counters is required. The Locking Totalizer locks all counters at every 100 counts. A release button quickly unlocks the Denominator for the next 100 counts. Individual percentages can be readily determined by dividing the counter readings by the number of hundreds counted. This feature positively prevents inadvertent over-counting. Non-Locking Totalizers are also available. They continuously accumulate the counts on the individual counters without the operator having to unlock the machine after each 100 counts.

Monitor vapor levels, simply and effectively.

Airchek Badges provide an innovative, simple and effective system for monitoring vapor levels, including:

  • Formaldehyde

The badges are simply clipped on to the technician's clothing and a record is kept of name, location and time, providing continuous sampling for personal monitoring and allowing the measurements required under Government regulations.

One badge provides continuous sampling over 8 hours. A second badge can be used to supply information for analysis of 15-minute peak exposure periods.
