There are many different tools that can be used for measurement, but the degree of accuracy is dependent upon the tool. For example, a ruler can measure distance with a good degree of accuracy, but for a more precise measurement a caliper should be used. The difference between a brass pressure sensor and a stainless steel pressure sensor is similar if we think about it in these terms:

• Stainless steel body, with high quality sealing which makes it impervious to fluids.
• Weather resistant connector and pins included
• Includes 1/8" NPT to -4 AN adapter included
• Accurate to 1% margin of error.
