pengenalan
Atago AES-421 Digital Salt-Meter ES-421 is a precision instrument designed for accurately measuring the level of salinity in various solutions. Utilizing a conductivity method, this device provides reliable salt concentration readings for a wide range of soluble materials, including dilute solutions of soy sauce, ketchup, mayonnaise, Worcester sauce, and squeezed juices from pickles. Its funnel-shaped sensor section ensures efficient sample application and measurement.
Figure 1: The Atago AES-421 Digital Salt-Meter ES-421. The device is white with a black and grey control panel. The digital display shows a temperature of 20.3°C and a salt percentage reading of 1.95%. Below the display are two buttons: 'START/OFF' and 'ZERO'. The sensor section is visible on the right side of the device.
Persediaan
Before initial use, ensure the device is properly prepared.
- Membongkar: Carefully remove the AES-421 Salt-Meter from its packaging. Inspect for any visible damage.
- Pemasangan Bateri: Locate the battery compartment, usually on the back or bottom of the unit. Insert the required batteries (e.g., AAA or AA, refer to specific product labeling if available) ensuring correct polarity. Close the compartment securely.
- Kuasa Awal Hidup: Tekan ke MEMULAKAN button to power on the device. The display should illuminate.
- Penentukuran Sifar: For accurate measurements, perform a zero calibration.
- Ensure the sensor section is clean and dry.
- Apply a small amount of distilled water to the funnel-shaped sensor section.
- Tekan ke SIFAR button. The display should show 0.00% or a similar indication of zero.
- Rinse the sensor with distilled water and dry thoroughly after calibration.
Arahan Operasi
Follow these steps to obtain accurate salt concentration readings:
- Sediakan Sample: Pastikan sample to be measured is homogeneous and free of large particles. For highly concentrated samples, dilution may be necessary to fall within the measurement range of 0.0 to 10.0% salt concentration.
- Bersihkan Sensor: Before each measurement, clean the funnel-shaped sensor section with distilled water and dry it thoroughly with a soft, lint-free cloth.
- Mohon Sample: Place a small amount of the prepared sample into the funnel-shaped sensor section. Ensure the sample completely covers the sensor electrodes.
- Take Reading: The device will automatically display the salt concentration percentage (Salt %) and temperature (°C) on the digital screen. Allow a few seconds for the reading to stabilize.
- Rekod Data: Note down the displayed salt concentration and temperature.
- Penderia Bilas: Immediately after each measurement, rinse the sensor section thoroughly with distilled water to prevent residue buildup. Dry the sensor completely before the next measurement or storage.
- Matikan: Tekan ke MEMULAKAN button to turn off the device when not in use to conserve battery life.
Pertimbangan Penting:
- The measurement range is 0.0 to 10.0% salt concentration.
- Temperature compensation is typically automatic, but extreme temperature variations in samples can affect accuracy.
- Always ensure the sensor is clean and dry before and after use.
Penyelenggaraan
Proper maintenance ensures the longevity and accuracy of your Atago AES-421 Salt-Meter.
- Membersihkan Sensor: After each use, rinse the funnel-shaped sensor section with distilled or deionized water. Use a soft, lint-free cloth or tissue to gently wipe and dry the sensor. Avoid abrasive materials or harsh chemicals that could damage the sensor electrodes.
- Membersihkan Badan: Lap badan utama peranti dengan kain lembut,amp cloth. Do not immerse the device in water or use organic solvents.
- Storan: Store the salt meter in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure the sensor is clean and dry before storage.
- Penggantian Bateri: If the battery indicator on the display shows low power, replace the batteries promptly to ensure continuous operation and prevent data loss or inaccurate readings.
- Penentukuran Biasa: Perform zero calibration regularly, especially if you suspect inaccurate readings or after prolonged storage.
