Pressure gauges used in these environments must be able to withstand rigorous cleaning cycles, resist contamination from bacteria build-up and comply with strict sanitary standards. Ashcroft, a leader in pressure and temperature instrumentation, offers two sanitary gauges designed for these challenges: the [1032 Sanitary Pressure Gauge with Tri-Clamp® connections](https://www.ashcroft.com/products/pressure/pressure-gauges/1032-sanitary-pressure-gauge/) and the [1033 Sanitary Pressure Gauge with DIN 11851 hygienic unions](https://www.ashcroft.com/products/pressure/pressure-gauges/1033-sanitary-pressure-gauge/). Both models combine hygienic design with rugged performance, ensuring accurate readings in critical processes. Read this product review to explore the unique features, specifications and typical applications of each pressure gauge. At the end, you will also see a side-by-side comparison to help you determine which option is best for your sanitary process.  ## Ashcroft® 1032 Sanitary Pressure Gauge The 1032 is a 3A-compliant gauge designed for pharmaceutical, biotech and food processes that use Tri-Clamp® fittings as the standard. 1032 Product Features - **3A Sanitary Compliance**: Certified to 3A sanitary standard 74, aligning with FDA and GMP requirements. - **CRN certification** is available for applications in Canada. - **Tri-Clamp® Connections**: Available in 1½˝ or 2˝ fittings, widely used in North America for ease of installation and hygienic sealing. - **Electropolished Diaphragm (12–15 RA)**: Smooth, polished finish reduces the risk of bacterial buildup and makes cleaning more effective. - **CIP (Clean-in-Place) / SIP (Steam-in-Place) / Autoclave Compatible**: Handles repeated washdowns and sterilization cycles without compromising accuracy. - **Easy Zero™ Adjustment**: External zero adjustment on the 3½˝ dial enables quick recalibration in the field without removing the gauge, minimizing downtime. - ***PLUS!*™ Performance Option**: Adds internal dampening to stabilize pointer movement. This helps reduce pointer flutter from vibration or pulsation, extending instrument life in demanding processes. - **Ingress Protection (IP65 / IP54)**: Smaller dials (2½˝ and 3½˝) are sealed to IP65, offering dust-tight protection and resistance to water jets. The 4½˝ dial is available with IP54 (splash resistance) or IP65, ensuring reliable performance in washdown environments. - **Material Options**: Offered in 316L stainless steel or Hastelloy® C276 to resist aggressive media. - **Traceability**: Supplied with heat lot traceable material certificates for compliance in regulated industries 1032 Product Applications - **Pharmaceutical manufacturing** — sterile processes requiring validated CIP/SIP cycles. - **Biotech and medical equipment** — high-purity applications where contamination cannot be risked. - **Food and dairy processing** — hygienic monitoring supporting FDA and GMP compliance. - **Filtration systems** — ensures process integrity in water, air, and sterile filtration processes. Note: If there is high vibration in your application. If so, you will need to consider a fluid fill. Ashcroft offers various fill fluids for oxygen service or paint applications to mitigate the negative effects of vibration. ## Ashcroft® 1033 Sanitary Pressure Gauge The 1033 is a DIN 11851-compliant sanitary gauge designed for breweries, dairy and food processes where hygienic union (milk coupling) connections are the industry standard. 1033 Product Features - **DIN 11851 Hygienic Connections**: Available in DN 25, DN 40, and DN 50, providing global compatibility for food and beverage systems. - **Polished Diaphragm (15 RA)**: Smooth finish prevents contaminant buildup and supports effective sterilization. - **CIP (Clean-in-Place) / SIP (Steam-in-Place) / Autoclave Compatible**: Designed to endure frequent washdowns and sterilization, critical for dairy and brewery applications. - **Easy Zero™ Adjustment**: External zero adjustment (3½˝ dial) allows calibration checks and corrections without disassembly, reducing downtime. - ***PLUS!™* Performance Option**: Provides added vibration dampening, improving readability and reducing wear in systems with pulsating pressure. - **Ingress Protection (IP65)**: Fully sealed against dust and water jets, making it suitable for washdown and humid environments. - **Certificates Supplied as Standard**: Delivered with EN 10204 3.1 certificates of conformance for quality assurance. 1033 Product Applications - **Breweries**: Optimized for hygienic brewing systems with DIN 11851 connections. - **Food & dairy processing**: CIP/SIP compatibility reduces contamination risks during frequent cleaning. - **Pharmaceutical & cosmetics**: Hygienic stainless-steel design supports regulated environments. - **OEM sanitary equipment**: Trusted for machine builders serving global food and beverage sectors. ## Product Specification Comparison: 1032 vs. 1033 | **Specification** | **1032 Sanitary Gauge** | **1033 Sanitary Gauge** | | --- | --- | --- | | Dial Sizes | 2½˝, 3½˝, 4½˝ | 2½˝, 3½˝ | | Pressure Ranges | Vacuum, compound, up to 1,000 psi | Vacuum, compound, up to 600 psi | | Accuracy | 2½˝ & 3½˝: ±2.0% to ±2.5% of span (≤100 psi), ±1.5% of span (\>100 psi) 4½˝: ±1.5% of span | 2½˝ & 3½˝: ±2.0% to ±2.5% of span (≤100 psi), ±1.5% to ±2.0% of span (\>100 psi, depending on fill) | | Process Connections | 1½˝ or 2˝ Tri-Clamp® | DIN 11851: DN 25, DN 40, DN 50 | | Fill Options | Glycerin (USP food grade), food-grade silicone, Halocarbon®, mineral oil | Glycerin, food-grade silicone, Halocarbon®, mineral oil | | Case Style | Open front, polished stainless steel | Open front, polished stainless steel | | Window | Polycarbonate (2½˝ & 3½˝), glass (4½˝) | Polycarbonate (2½˝ & 3½˝) | | Wetted Materials | 316L stainless steel or Hastelloy® C276 diaphragm and housing | 316L stainless steel diaphragm and housing | | Weather / Ingress Protection | IP65 (2½˝ & 3½˝ dials); IP54 or IP65 (4½˝, depending on fill) | IP65 (all sizes) | | Compliance / Certification | 3A-74 sanitary compliance, CRN, RoHS | EN 10204 3.1 material certificates provided as standard | ## Ready to learn more?
