    Chemical-Level Indicators

    Check the level of liquids containing chemicals such as alcohol-based solvents, boric acid, and sodium bicarbonate. These indicators can be used in pressurized applications where overflow is a concern. All have an aluminum gauge shield that protects the glass window from impact. Clear liquids magnify a red line at the back of the window, so their levels are easier to see.

    Sanitary Gauge Guards

    Keeping corrosive substances from touching pressure gauges used in food-processing and pharmaceutical plants, these guards have a sanitary design. Made of 316 stainless steel, they won’t rust from frequent washdowns with harsh cleaners and sanitizers. They have continuously-welded seams and polished surfaces, so there aren’t any pits for bacteria to grow in. Removing them for cleaning and maintenance is easy thanks to their quick-clamp connection, which is sometimes called a tri-clamp.
    Also known as isolators and diaphragm seals, these guards have a 316 stainless steel gasket to shield the pressure gauges from corrosion. Before use, fill the guards with fluid such as glycerin or silicone that’s suitable for food contact.

    Chemical-Resistant Vertical-Mount Liquid-Level Gauges for Tanks

    Image of Product. Front orientation. Liquid-Level Gauges. Chemical-Resistant Vertical-Mount Liquid-Level Gauges for Tanks.
    With a stainless steel float and float rod, these gauges resist corroding from chemicals. Their indicator moves up as your tank fills. Check the indicator against the graduation marks to see how full your tank is and if you need to fill or drain it. Plastic protects the indicator's movement, saving you from inaccurate readings.

    High-Pressure Gauges for Chemicals

    A 316 stainless steel guard, also known as an isolator, protects the gauge from damage caused by corrosive chemicals. Gauges are commonly used with pumps, filters, regulators, and in process lines to measure and display pressures up to 2,000 psi.

    Low-Pressure Gauges for Chemicals

    A plastic or stainless steel guard, also known as an isolator, protects the gauge from damage caused by corrosive chemicals. Use them with pumps, filters, regulators, and in process lines to measure and display pressures.

    Vibration-Resistant Pressure Gauges for Chemicals

    These gauges have a glycerin-filled dial that reduces needle flutter for precise readings in high-vibration applications reaching 2,000 psi. A 316 stainless steel guard, also known as an isolator, protects the gauge from damage caused by corrosive chemicals. Use them with pumps, filters, regulators, and in process lines to measure and display pressure.
