Mi455 Mini-titrator for the determination of FREE & TOTAL SULPHUR DIOXIDE in wine analysis by Milwaukee

Mi455 is a user-friendly microprocessor-based mini-titrator for the determination of free and total sulphur dioxide in the process of wine making. This mini-titrator will give you direct readings with a range of 0 to 400 ppm.

The instrument comes with a pre-programmed analysis method for free and total sulphur dioxide measurements on wine sample.

Technically, sulphite is a salt or ester of sulfurous acid, but more commonly, sulfur dioxide (SO2). Sulfite is the most effective and widely used preservative in winemaking. It preserves by safeguarding musts and wines against premature oxidation and microscopic life forms that could otherwise spoil wine. It preserves a wine s freshness, helps maintain its color, and is essential for aging wines beyond their first year without deterioration. It also inhibits wild yeasts, thereby allowing cultured wine yeasts to dominate the fermentation. Sulfites may be "bound" or "free". Bound SO2 combines with aldehyde compounds, those most responsible for oxidation in wines.

Free SO2 results from the dissipation of active SO2 and is the only SO2 that provides antiseptic and oxidative protection to wines. The most efficient what to add free SO2 to a must, juice or wine is by adding dissolved potassium metabisulfite to it. The effectiveness of free SO2 is dependent on the pH of the media to which it is added.

EP-10 DS Conductivity Meter: 0-10, 100, 1000, 10,000 AμM/AμS by Myron L

READINGS YOU CAN COUNT ON

No water supply is completely pure. Every industrial, commercial, or natural source contains dissolved solids or salts. These impurities contribute to scale, corrosion, poor taste, and environmental pollution that endanger animal and plant life.

Myron L Company has two proven ways to measure such impurities. Our DS Meters provide fast, accurate, on-the-spot measurement of total dissolved solids (TDS) or conductivity. pDS Meters test conductivity or TDS, plus pH. Readings from their highly stable circuitry help prevent equipment damage, assure product quality, and verify in-line instrumentation in a wide range of applications.

RELIABILITY BUILT IN

Breakage is one of the major causes of sensor failure in a typical pH or conductivity instrument. Myron L instruments provide maximum protection for both the pH and conductivity electrodes inside the cell cup. The userreplaceable pH electrode features a chemical resistant, liquid junction.

UNIQUE FIELD-TESTED DESIGN

Our unique, durable, field-tested design has evolved over more than 40 years, making Myron L instruments among the most reliable and popular of their kind in the world.

They're lightweight and compact, Yet Myron L's DS and pDS Meters are also tough, with rugged, taut-band meter movements.

Put our meters to the test. Even after years of rough field service, they'll surpass your expectations of accurate, reliable readings.

0614 0072 Pt100 Digital Air Probe (need cable 0430 0100) by Testo

The new digital air temperature probe enables precise measurement of air temperature. To guarantee a quick response time, the Pt100 sensor is exposed and is protected against impact and contact by a guard.

You can also use immersion and penetration probes to measure air temperature. However, please note that the specified response time of the immersion/penetration probe refers to measurements in water. For measurements in air, the response time is around 40 - 60 times higher. This is because in immersion/penetration probes the sensor element is built into the probe shaft, and the probe shaft still needs to reach the actual temperature. Only then is this passed on to the sensor element.

In the air temperature probe, however, the sensor is exposed. Therefore the temperature to be measured directly encounters the sensor element. Consequently, compared with the immersion/penetration probe, the air temperature probe can achieve shorter response times when measuring air temperature.

The air temperature probe is a digital probe with an intelligent calibration concept. You can adjust the probe using the EasyClimate software and achieve a zero-error display.

Applications

The Pt100 air temperature probe is suitable (in combination with the measuring instrument) for industrial and laboratory applications such as:

• Calibrating stationary sensors
• Monitoring production processes / production facilities
• Monitoring process temperatures
• Reference measurements in the calibration laboratory

• Pt100 probe for air temperature measurements
• Quick response time
• With a guard to protect against impact and contact
• Measuring range: -100 to +400 °C

Includes:

Pt100 air temperature probe with guard including instructions for use.
