The Visi–Float flowmeter bodies are cut and precision machined from solid, clear acrylic plastic blocks. This construction not only produces a handsome finished product, but permits complete visual inspection. As a result, the Visi-Float flowmeters are especially popular for medical and laboratory equipment applications. Scales are easy to read - The front scale location and white background provides excellent visibility. The direct reading scales are hot stamped into the plastic and will not wear off. Mid-range calibration is established with a master flowmeter. Accuracy is ±5% of full scale for VFA models, ±3% for VFB. Scales average 2" long on the VFA models, 4" long on VFB. Durable and attractive construction - The machined acrylic bodies of the Visi-Float® flowmeters are practically unbreakable. Fabrication is backed by over 60 years of experience in acrylic instrument machining. The tapered bore is precision machined to a smooth surface that provides perfect visibility of the indicating float. The VFA and VFB models are available with either brass or stainless steel inlet and outlet connections and are tapped for 1/8" NPT thread. VFB models 85 and 86 have either 1/4" back or 3/8" end connections. All standard models employ Buna-N O-rings for leak proof operation and are available with either back or end connections for horizontal or vertical piping. Precision metering valves in brass or stainless steel are available for most VFA and VFB models. Easy installation - All Visi–Float® flowmeters have metal mounting inserts on rear for panel mounting. They can also be supported directly by system piping.

Such as hot water Water flow rate: TDS pen can not be used to measure a large body of water sloshing. Regional: Each different regions, cities, due to the different pipes and water, TDS value will be different. PH TasterCalibration methods: 1. An appropriate amount of 6.86 / 4.00 and 9.18 standard buffer solution were poured into clean different beaker, mix in 250ml distilled water. 2. Touch the ON / OFF button, turn on the power. 3. Place the electrode insert PH6.86 standard buffer solution and shake gently until the display value is stable. 4. Press "CAL" key (in 6.86 solution), for about 5 seconds, the instrument enters the automatic calibration until the displayed value to the standard buffer solution PH values, the 6.86-point calibration is complete. 5. Rinse the electrode, the electrode into PH4.00 standard buffer solution and shake gently until the display value is stable. 6. Double-click the "CAL" key (in 4.00 solution), with steps 4, complete PH4.00 point correction. 7.

Compex electrodes are used during muscle stimulation with Compex devices. The electrodes play a big part in the Compex muscle stimulation session. They are the points where the pulses are transmitted to your motor nerves, and ultimately your muscle fibers. If the Compex electrodes aren't adhering properly, the electrical pulse can't be delivered at the intensity needed to work your muscle at peak effectiveness.
