SENCTRL 0-100 Psi Glycerin Filled Gauge
The SENCTRL 0-100 Psi glycerin-filled gauge features brass and stainless steel wetted parts to measure non-corrosive liquids and gases, including water and oil. It comes in a 304 stainless steel case for corrosion resistance and reduces pointer flutter thanks to glycerin filling. It uses a 2.5-inch dial with dual scale (0-100 psi / 0-700 kPa) for versatility across PSI and kPa systems. With an accuracy of ±3/2/3% across its range, this model suits water pumps, well pumps, RV hoses, pneumatic lines, and gas pressure tests where dynamic conditions are common.
SENCTRL 0-160 Psi Glycerin Filled Gauge
This glycerin-filled gauge provides a broader 0-160 psi (0-1100 kPa) measurement range in a compact 2.5-inch dial. Its brass and stainless steel wetted parts handle non-corrosive liquids and gases, including water, oil, and related test media. The 304 stainless steel case protects against corrosion, while glycerin filling dampens pulsations and vibrations, preserving the internal mechanism. It is well-suited for portable air compressors, water pumps, wells, tanks, and RV regulators where steady readings are critical in fluctuating conditions.
MEASUREMAN 0-100 Psi Glycerin Filled Gauge
The MEASUREMAN 0-100 psi gauge combines a glycerin-filled mechanism with a 2.5-inch dial and a 304 stainless steel case. The dual-scale readout (psi and kPa) enables quick cross-reference in mixed unit environments, making it practical for both industrial and home use. Its 1/4″ NPT lower mount ensures straightforward installation on pumps, lines, and test rigs. This model is designed to minimize the effects of vibration and pulsation on measurement accuracy in dynamic settings such as water systems and air lines.
MEASUREMAN 2-1/2″ Glycerin Filled, 0-200 Psi
This MEASUREMAN model features a 2-1/2″ dial, glycerin fill, and a 3/4″ female hose thread adapter for direct faucet or hose connections. It covers a 0-200 psi (0-1400 kPa) range, making it suitable for irrigation systems, garden setups, and household pressure testing. The brass components with a stainless steel case offer robust performance in wet or humid environments, while glycerin filling reduces pointer flutter and enhances longevity under pulsating flows. It is particularly useful for monitoring water pressure in pumps and pipelines.
MEASUREMAN 0-60 Psi Glycerin Filled Gauge
This compact gauge delivers reliable liquid and gas pressure readings from 0 to 60 psi with a 2-1/2″ dial. Its glycerin-filled design dampens vibrations, reducing needle jitter in systems with pulsating flows. The 1/4″ NPT lower mount provides flexible installation, while the stainless steel case ensures durability in challenging environments. It suits low-pressure monitoring in small-scale pneumatic and hydraulic circuits, as well as household irrigation lines where precise, stable readings matter.
Saysurey 6 Pcs 0-100 Psi Glycerin Filled Gauges
The Saysurey pack includes six glycerin-filled gauges, each with a 2.5″ dial and a 0-100 psi range. The 1/4″ NPT lower mount and a stainless steel case provide robust construction for water, oil, and air testing. Glycerin filling mitigates pointer flutter and helps the gauge withstand vibration and pulsation in dynamic environments. This option is ideal for bulk inventory in maintenance shops, construction sites, or educational demonstrations where multiple gauges are needed for testing various circuits and devices.
MEASUREMAN 0-15 Psi / 100 kPa Gauge
This MEASUREMAN gauge covers a narrow 0-15 psi (0-100 kPa) range with a glycerin-filled mechanism and a 2-1/2″ dial. The 1/4″ NPT lower mount supports straightforward installation in compact installations where precise, low-pressure readings are essential. The stainless steel case protects against corrosion, making it suitable for gas and non-corrosive liquids. It balances readability with resilience in laboratory test rigs or small-scale irrigation and pneumatic systems requiring steady pressure monitoring.
MEASUREMAN 4″ Dial Glycerin Filled Gauge
With a larger 4″ dial, this MEASUREMAN gauge focuses on easier readability for higher-pressure applications up to 160 psi. The 1/4″ NPT lower mount and stainless steel case offer durability in plumbing, gas lines, and industrial settings where large, legible readings help operators respond quickly. Glycerin filling reduces the impact of vibration and pulsation, stabilizing readings in systems with fluctuating pressures, such as air compressors, water heaters, and irrigation manifolds.
Buying Guide: Key Considerations For Glycerin Filled Pressure Gauges
- Mounting and connection type: Choose lower mount or hose thread (1/4″ NPT or 3/4″ female hose thread) based on your existing fittings and installation space. Lower mounts are compact, while hose thread adapters enable direct attachment to hoses or fixtures.
- Dial size and readability: Larger dials (2.5″ to 4″) offer easier reading in bright environments or at a distance. Consider whether dual-scale (psi/kPa) readouts will simplify operation in your locale.
- Media compatibility: Ensure brass and stainless wetted parts handle your fluids or gases. Glycerin-filled gauges are suited for non-corrosive liquids and gases commonly found in water systems, air lines, and oil testing.
- Pulsation and vibration resistance: Glycerin filling dampens needle flutter, improving stability in pumps, compressors, irrigation systems, and pipelines where pressure spikes are frequent.
- Durability: A stainless steel case provides corrosion resistance, while a robust gasket and seal design protects against leaks in wet or dusty environments.
- Accuracy and temperature effects: Look for gauges with acceptable accuracy (commonly ±3% to ±3/2/3%) across the operating range. Consider operating temperature ranges if you expect extreme conditions.
- Cost and quantity: For maintenance shops or educational settings, bulk packs may reduce per-unit costs. For single installations, a reliable individual unit may suffice.
- Certification and standards: If your applications require compliance, verify any relevant certifications or industry standards for pressure measurement devices in your region.
Glycerin-filled gauges offer a practical balance of accuracy, durability, and resilience against pulsation. By evaluating mounting options, dial readability, and media compatibility, you can select gauges that provide stable readings across a variety of water, air, and test environments.
