The Cannon ZCAC-5 Zeitfuchs cross-arm viscometer has a 60 to 300 centistokes (cSt) viscosity measuring range and is suitable for the measurement of either transparent or opaque Newtonian fluids such as fuels and lubricants. It uses a viscometer constant of 0.3 centistokes per second (cSt/s) for calculating kinematic viscosity of sample sizes as small as 1.0mL. The ZCAC-series size 5 viscometer uses a 230mm depth water bath (not included) for temperature-control testing and a vacuum (not included) to draw a sample up for timed testing between two sets of printed marks. It includes an ASTM International certificate of calibration. This calibrated capillary-style viscometer meets the ASTM International D446 standard for viscometers and the D445 standard for testing viscosity. A viscometer, also called a viscosimeter, is an instrument used to measure the friction caused by the relative motion of a Newtonian fluid and a known surface, and is usually expressed in units of poise (P), centipoise (cP), pascal seconds (Pa s), and millipascal seconds (mPa s). Viscometers have several forms, including but not limited to falling ball, rotational, vibrating, capillary, funnel, and bubble. A falling ball viscometer measures the time it takes for a ball of known diameter and density to fall through fluid in a cylinder of known diameter. A rotational viscometer measures the force required to stir a fluid. A vibrating viscometer measures the power input necessary to keep the oscillator vibrating at constant amplitude while immersed in a fluid. A capillary viscometer has a narrow-bore vertical section with two printed marks that measure time required for a known volume of fluid to fall a known distance. A funnel viscometer, such as a Ford, Zahn, or Shell cup, measures the time it takes a known volume of fluid to flow from the base of a cone through a short tube. A bubble viscometer measures the time required for an air bubble to rise through a fluid. Viscosity measurements are used in laboratories, research and development, proces...

Manufacturer: Hanna Instruments Brand: Hanna Instruments Model: HI1288

The Hanna Instruments HI 1288 is a pH and electro-conductivity (EC) electrode for HI 991300 and HI 991301 portable meters and has a single cloth junction, Automatic Temperature Compensation (ATC), polyvinyl chloride (PVC) body, flat tip, internal amplifier, Deutsches Institut für Normung (DIN) connector, and a 1.2m (4') seven-pole cable. A pH electrode is commonly attached to a pH meter to measure the pH of a substance such as water, food, beer, or wine in lab, industrial, and food applications. An internal thermometer sensor in this electrode provides ATC for accurate readings in fluctuating temperatures. The single cloth junction reduces contamination. The PVC body with 8.5mm spherical tip is for general purpose and field applications. An internal amplifier provides a strong low impedance signal from the electrode to the HI 991300 and HI 991301 portable meters. A DIN connector provides a tight cable connection and the electrode comes with a seven-pole 1.2m (4') cable.

All electrodes are probes or sensors, but not all probes are electrodes or sensors. Probes, such as temperature probes, are used to penetrate a material for measurement. Common electrode types are pH, total dissolved solid (TDS), and ion selective electrode (ISE). Electrodes can be half-cell or full-cell (also called combination) types. They can be refillable or non-refillable. Housing material is typically glass or epoxy, and sensors are commonly made with stainless steel or a glass bulb. pH electrodes, which measure the pH of a substance, often have a glass bulb. The bulb senses hydrogen ions, and generates a millivoltage that is picked up by the filling solution and transferred to a wire that conn...

Nephelometric or transmittance measuring-the nephelometric measurement at 90° scattered light is advantageous for lower turbidity, whereas the transmission measurement at 180° is beneficial for medium to high turbidity values: With increasing turbidity, restray and scattering effects between particles are growing bigger. The reduction of light intensity in this case leads to a more accurate result than a 90° nephelometric measurement. Therefore, lab meters for high values are equipped with several measuring options: ratio modes calculate the final result from different measured angles. For ratiometric measurements, there is no specific standard method to be followed; rather, procedures are established by the application or industry. White light has a higher sensitivity for small particles, however, the inherent coloration of the solution has a stronger disturbing effect in this case. The IR measurement is required by DIN ISO, the white light measuring by US EPA.
