Piccolo 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.
Features:
- 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.

pH Indicator Papers - Test Papers
1. 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 6x85 mm.

2. 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.

Anemometer
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.
Measurements: 4.5"x2.5"x1.5".

FreezGuard™ Alarm
Alarm will Sound for Up to Three Days
Prevent costly, time consuming sample loss with this practical battery operated system. The FreeGuard™ Alarm monitors freezers and coolers and detects any variance from temperatures between -20°C and 13°C (-5°F to 55°F), ±1°C, which are preset by the user. The resonant alarm will continue to sound for up to three days if the temperature falls out of the pre-set range. Should the temperature correct itself, an LED will indicate that a variance has occurred. The alarm can be reset manually. A beep will signal when the 9V battery (not included) is low. For added protection, and extra life, a second battery can be connected. The unit mounts with self-adhesive tape or screw. Unit comes with a 3 meter probe lead, and measures 86W x 35D x 26mmH (3 5⁄16 x 11⁄2 x 5 1⁄16). The weight without the battery is 144 g (5.1 oz).

Temperature
Tester; Checktemp 2
Checktemp2 is a high accuracy thermometer with a folding 110mm long probe. The probe has been specially designed to fold at different angles for measurements in difficult places. Checktemp 2 utilizes a hightech NTC thermistor sensor to measure the temperature. Unlike most other electronic thermometers, Checktemp 2 has a unique Calibration Check feature. Simply open the battery compartment and turn the Cal-Check switch on. The display will show a value between -0°C and +0.3°C. This means your meter is still within specifications of +/-0.3°C.
Checktemp 2 is destined to make glass thermometers obsolete. Glass thermometers contain lead and the measurement media is either mercury or alcohol. These materials are undesirable in today’s work place.
