PT218 E-Ink Thermo-Hygrometer with Max and Min Readings Malaysia
PT218 E-Ink Thermo-Hygrometer with Max and Min Readings Malaysia
Content
The PT218 Temperature and Humidity Detector combines an E-ink display, current room readings and maximum and minimum temperature and humidity values in a compact unit.
For homes and offices in Malaysia, it offers a clear local display without requiring an app. Its published ±0.5°C temperature accuracy makes it an option to consider when comparing compact thermo-hygrometers for everyday room checks.

The catalogue marks batteries as optional. Confirm battery inclusion and the supplied mounting accessories before ordering.
Current Readings and Recorded Extremes
The PT218 displays current temperature and humidity prominently, with smaller maximum and minimum readings below.
This arrangement helps users check current conditions and review recorded extremes on the same screen. For example, an office user can compare the present reading with the highest and lowest values captured during the relevant memory period.
The illustration includes a “24hrs” indicator, but the supplied specification does not explain whether this represents rolling 24-hour values or a daily reset cycle. Confirm the memory behaviour and reset procedure before interpreting the readings.
E-ink Display for Local Viewing
The E-ink screen presents measurements in a high-contrast layout. The product illustration shows a desktop support arrangement, making it suitable to consider for shelves, desks and bedside tables.
The catalogue does not specify a backlight, screen-refresh interval or viewing-distance rating. Buyers who need to read the instrument in a dark room should confirm lighting requirements before purchase.
WiFi, Bluetooth and remote notifications are not listed. The PT218 should be selected as a local-display instrument unless additional functions are confirmed for the supplied version.
Understanding Accuracy and Resolution
The PT218 lists 0.1°C resolution and ±0.5°C temperature accuracy.
Resolution describes the displayed increment. Accuracy describes the published measurement tolerance. A one-decimal-place reading should therefore not be interpreted as accurate to 0.1°C.
Humidity accuracy is listed as ±5%, but the page does not provide a separate humidity-resolution specification or detailed test conditions.
For applications with strict environmental limits, request the complete accuracy specification and any required calibration documentation.
Comfort Indicator and Low-Battery Alarm
A comfort emoji provides a visual reference alongside the numerical readings. Its temperature and humidity thresholds are not defined on the supplied page.
Use the actual measurements when comparing room conditions against a particular requirement. The comfort symbol should remain supplementary information.
The low-battery alarm helps indicate when attention is needed, although the catalogue does not explain whether this is a display warning or an audible signal.
Placement for Homes and Offices
For a bedroom or workspace in Puchong, Selangor or Kuala Lumpur, position the PT218 away from direct sunlight, hot equipment and direct air-conditioner airflow.
Keep the sensing openings clear and allow the readings to stabilize after moving the instrument. The catalogue does not specify a response time.
For several monitoring points in Johor or Penang, use consistent placement and label each instrument's location. This helps distinguish differences between rooms from changes over time.
Using the PT218 Around Storage Areas
The catalogue lists food storage among its applications. Before selecting it for a particular storage process, compare the expected conditions with its -15°C to 50°C temperature range and 20-95% RH humidity range.
The supplied page does not establish waterproof construction, remote probes or continuous data logging. It also does not specify suitability for condensation.
Where records are required for inspections or quality control, confirm whether a dedicated data logger is needed.

Choose the PT218 when an on-device display and recorded extremes meet the requirement. Specify recording intervals, timestamps and export formats separately if those functions are needed.
Frequently Asked Questions
Does the PT218 show Celsius and Fahrenheit?
Yes. Both temperature units are advertised.
What batteries does it use?
The catalogue specifies two 3 V CR2450 coin cells. Confirm whether they are included.
Does it display maximum and minimum readings?
Yes. Maximum and minimum temperature and humidity functions are listed.
Are the extremes reset every 24 hours?
The illustration shows “24hrs,” but the exact memory and reset behaviour require confirmation.
Does it have WiFi or Bluetooth?
Neither connection is listed on the supplied page.
Does it have a clock or alarm clock?
Timekeeping and alarm-clock functions are not listed for the PT218. The advertised low-battery alarm is a separate function.
Is a calibration certificate included?
The packing list names the instrument and product description. A calibration certificate is not listed; specify any documentation requirements before ordering.
