tool

1. ___ pressure gauge
2. ___ thermometer
3. ___ flow meter
4. ___ ph meter
5. ___ control chart
6. ___ sampling bottle
7. ___ calibration device
8. ___ laboratory analyzer
9. ___ inspection log

function
a. measures the temperature of a process or product.
b. visually inspects and records process data for accuracy and compliance.
c. used to measure and display pressure within tanks, pipes, or reactors.
d. graphs used to track process stability and identify abnormal variations.
e. checks the acidity or alkalinity level of liquids during testing.
f. used to collect representative samples of materials for lab testing.
g. used to compare instrument readings to a standard reference for accuracy.
h. tests material composition, purity, or quality before product release.
i. measures the rate at which material moves through a process line.

Explanation:

• Pressure Gauge: As the name suggests, it is used to measure pressure. Option C clearly states "Used to measure and display pressure within tanks, pipes, or reactors", which matches its function.
• Thermometer: A common tool whose primary function is to measure temperature. Option A "Measures the temperature of a process or product" is the correct match.
• Flow Meter: The key word is "flow", which relates to the rate of movement. Option I "Measures the rate at which material moves through a process line" aligns with its function.
• pH Meter: pH is a measure of acidity or alkalinity. Option E "Checks the acidity or alkalinity level of liquids during testing" is appropriate.
• Control Chart: It is a graphical tool. Option D "Graphs used to track process stability and identify abnormal variations" fits.
• Sampling Bottle: Its purpose is sampling. Option F "Used to collect representative samples of materials for lab testing" is correct.
• Calibration Device: Calibration is about comparing to a standard. Option G "Used to compare instrument readings to a standard reference for accuracy" is right.
• Laboratory Analyzer: Analyzers test materials. Option H "Tests material composition, purity, or quality before product release" is a good match.
• Inspection Log: Logs are for recording. Option B "Visually inspects and records process data for accuracy and compliance" is the right fit.
