MA886 Digital Nacl Refractometer by Milwaukee

The MA886 is an optical instrument that employs the measurement of the refractive index to determine sodium chloride concentration in aqueous solutions used in food preparation.

It is not intended for sea water salinity measurements. The measurement of refractive index is simple and quick and provides the user an accepted method for NaCl analysis. Samples are measured after a simple user calibration with deionized or distilled water. Within seconds the instrument measures the refractive index of the solution. The digital refractometer eliminates the uncertainty associated with mechanical refractometers and is easily portable for measurements where you need them.

The instrument utilizes internationally recognized references for unit conversion and temperature compensation. It can display the measurement of NaCl concentration 4 different ways: g/100 g, g/100 mL, Specific Gravity, and °Baumé.

Temperature (in °C or °F) is displayed simultaneously with the measurement (on 3 of the ranges) on the large dual level display along with icons for Low Power and other helpful message codes.

Key features include:

• Automatic Temperature Compensation (ATC)
• Battery operation with Low Power indicator
• Automatically turns off after 3 minutes of non-use

93831-70 Gen-Purpose RTD Probe 100 Ohm ANSI 3-Blade Connector, 10" L by Digi-Sense

Maximum error for probe assembly is ±1.1°C + 0.12% of reading below 300°F, ±0.35% of reading above 300°F. Alpha coefficient is 0.003850 Ω/Ω/°C (DIN IEC 751). Resistance at ice point (0°C) is 100 Ω.

Note: Time constant is the time required to reach 63.2% of the new reading. To determine how long it will take to reach 99% of the new reading multiply the time constant by five.

Note: The temperature range is for the probe tip only. The handle material may be affected if the probe is rated higher than the handle depending on exposure time, application, and handle material. ABS handles are rated to 220°F (104°C); PVC handles are rated to 200°F (93°C); Stainless Steel handles are rated at 450°F (232°C); Mini Connectors are rated to 392°F (200°C).

• Time Constant: 1-3 seconds or greater
• Custom designs or changes to this product are available upon request

856302 Chemcassette Tape, Chlorine/Chlorine Dioxide by Honeywell Analytics

Chemcassette® is the unique trademarked name for a calibration free toxic gas detection method that uses an optical scanning system to detect the presence of gas by a colour change on the specially chemically impregnated paper tape. Chemcassette® technology is highly specific and reacts extremely fast to the presence of parts per billion (ppb) levels of many hazardous gases. Over 200,000 points of gas detection are currently maintained by the Chemcassette® sensing technology at any given time around the World in some of the most critical safety applications possible.

Each Chemcassette® is manufactured to traceable ISO 9000 manufacturing standards by a world class team of highly trained chemists and each batch is calibrated with ultra pure gas that is traceable to nationally accepted standards. This means that the end user does not have to provide calibration facilities themselves thereby saving cost and reducing risks to their own staff.

Efficient high volume manufacturing techniques means that there is always available Chemcassette® in stock that can be shipped anywhere in the World so that our customers are never left without adequate safety cover. Application support with expert gas detection chemists is available by phone and e-mail and is supported with many years of technical application notes and help to diagnose common support issues.

Should there be any concern regarding the performance of an individual Chemcassette®, a free of charge evaluation will be performed to trouble shoot the observed scenario using the award winning quality management system "Customer Discrepancy Report" CDR. Every CDR completed by a customer is guaranteed a full response and the outcome is reported directly back to the end user to ensure a complete resolution process.

Each Chemcassette® is backed with a full warranty and we have over 20 years of experience regarding the quality control of our proven sensing technology.
