湿度テストを簡素化 - 校正のヒントとリソース

Relative humidity (RH) moisture testing in concrete requires a properly calibrated in-situ probe to ensure accuracy.

Calibration protects you in case moisture problems come up later, and compliance with ASTM F2170 requires calibration and documentation of it.

Any way you look at it, you want to make sure the in-situ probes you use to measure moisture in concrete are calibrated to requirements.

As a reminder, in-situ probes are placed in holes in the concrete slab, at the right testing depth, to measure the RH within it. In-situ RH testing is widely considered the most reliable way to determine the moisture condition of a concrete slab.

キャリブレーションとは実際には何を意味するのでしょうか?

An in-situ RH probe has two main components: a sleeve and a sensor. The sleeve is installed in the concrete slab. The sensor is placed in the sleeve for performing the actual RH test. The sleeve protects the sensor and helps with proper equilibration for the most relevant RH reading.

The sensor needs to be properly calibrated before use. Calibration ensures that the sensor will provide sufficiently accurate relative humidity measurements to meet the ASTM F2170 standard for relative humidity testing. ASTM F2170 allows more than one way to check calibration, including using a saturated salt solution.

ワグナー・ファクター – ラピッドRH^®

Wagner Meters developed its RH testing products with easy calibration in mind. Its Rapid RH Smart Sensors, both the Rapid RH L6 and the Rapid RH 5.0, are calibrated at the factory, so they’re ready to use right out of the box.

Rapid RH sensors come with a certificate of calibration, the calibration documentation ASTM F2170 calls for.

The Rapid RH L6 Smart Sensor makes it especially simple. Because it’s a single-use sensor, it never needs a calibration check, which makes it a good fit for contractors and flooring installers.

再利用可能なセンサーの校正の維持

Rapid RH L6スマートセンサーはXNUMXつの試験場所での使用を想定して設計されていますが、再利用可能なセンサーは複数の試験場所で使用できます。XNUMXつの場所に設置して測定値を取得した後、取り外して別の場所に設置することができます。

一部の建築検査官、床検査官、エンジニアリング会社、一部の QC 担当者にとっては、Rapid RH 5.0 のような再利用可能なシステムが役立つかもしれません。

However, to maintain ASTM F2170 compliance, the calibration of a reusable sensor must be checked within 30 days before it’s reused. Because of the extra time and attention that takes, a single-use system is usually the best choice for most contractors and flooring installers.

To keep those calibration checks simple and quick, Wagner Meters designed the 再利用可能なRapid RH 5.0スマートセンサー with that process in mind.

Each Rapid RH 5.0 reusable sensor comes with its own patented EasyCare CalCheck™ protective storage unit, which holds a 75% RH salt solution for checking calibration.

EasyCare CalCheck保管チャンバーは、Rapid RH再利用可能スマートセンサーを最適な状態で保護・保管します。これにより、各センサーの寿命が延び、校正チェックにかかる時間が大幅に短縮されます。

Each Rapid RH 5.0 sensor must be replaced annually with a newly certified sensor to maintain ASTM F2170 compliance.

The innovative design of the Rapid RH 5.0 makes it a great choice for anyone who prefers using a reusable RH sensor. And if you prefer a sensor that never needs a calibration check, the single-use Rapid RH L6 is the way to go.

Bottom line: reusable sensors cost more up front and take more time to use and maintain, but they can be used at as many test sites as needed for 12 months before any additional investment.

選択するセンサーの種類よりも重要なのは、どのテストを採用するかを選択することです。

Remember: RH testing is your best option for protecting the integrity of your work. When your work and reputation rest on the results of your moisture testing, a certified, accurate in-situ RH probe gives you the confidence you need.
