08141-02 TI.30 9 Back-Con Bimetal Thermometer, Dial 3", 9" L/25-125F/-5-50C by Digi-Sense

Accuracy is ±1% full-scale when stem is immersed 2" in liquids or 4" in gases (immerse models with a 2.5" stem length 2" in gases). Measured stem length from the top of the threads to the bottom tip of the stem. Stem dia is 0.25"; threaded connection is 1/2" NPT(M). All thermometers meet or exceed ASME B40.3 standards. Maximum environmental temperature for glass lens thermometers is 500°F (148°C).

Key Features

• Greater temperature range
• Anti-parallax dial for accurate readings
• Hermetically sealed per ASME B40.3 standard to prevent fogging and protect against tough environments
• Rugged 304 stainless steel construction with a clear glass lens
• Recalibrate using the external reset screw

Part Number: P19711.62VA

56B010210 Dip Sldies: Lovibond Yeasts, Molds, Fungi & TVC, 10 pk by AquaPhoenix

The TTC/MALT dipslide allows convenient enumeration of aerobic microorganisms (TVC) as well as fungi, moulds and yeasts in a single test. The dipslide is prepared with nutrient TTC agar on one side (responsive to aerobic microbes) and an acidic malt agar which selects for the growth of yeasts and moulds. The additive in the nutrient agar reacts with enzymes produced in aerobic respiration to produce a colour change from white to red, allowing easy enumeration.

• Determine aerobic and anaerobic bacteria levels
• Early indication of bacteria proliferation
• Results in 48 hours
• Inexpensive
• Easy-to-Use
• Excellent for trend analysis
• Best used in: waters and surfaces

Dipslides are supplied in boxes of 10 and come with instructions to determine the activity of aerobic & anaerobic bacteria.

TDS3000/G Conductivity Solution, 3000ppm/3900uS, 1Gal by Sensorex

TDS/Conductivity instruments and sensors must be calibrated together. For a single-point calibration, select the one solution that approximates the expected conductivity or ppm level of total salts. Mixed Salt standards are the most frequently used in the field to sample naturally occurring water sources, boiler feed water, or cooling tower water. Typical river water, well water, or lake water sample will contain a mixture of several different salts. Sensorex Mixed Salt standards simulate a "Natural" mixture of common salt compounds found in these sources. Sodium sulfate, sodium bicarbonate, and sodium chloride salts are blended to provide a representative value. There are certain applications where Single Salt Solutions are preferred. NaCl Solution is routinely used to calibrate instruments measuring Sea Water or brackish water samples. Reagent grade salt and high resistivity DI water is compounded for accurate results. KCI Single Salt Solution may be used with conductivity meters that read directly in Siemens or Ohms. KCI (potassium chloride) is established as an international calibration standard for conductivity measurement. Choose the conductivity calibration solution that is right for your application.
